+  - The functions u16_to_u32, u16_to_u8, u8_to_u32, u8_to_u16 now fail when
+    the argument is not valid. Previously, they returned a converted string
+    where invalid parts were each replaced with U+FFFD.
+  - The function u8_mbsnlen now counts an incomplete character at the end
+    of the argument string as 1 character. Previously, it could count as 2
+    or 3 characters.
+  - The return value of the u8_stpncpy, u16_stpncpy, u32_stpncpy functions
+    was incorrect.
+  - The u8_strcoll, u16_strcoll, u32_strcoll now try harder to give a non-zero
+    return value.
+* Portability to MacOS X 10.6 and Cygwin 1.7.
+
+New in 0.9.2:
+* The function uc_locale_language now uses the locale of the current thread,
+  if a thread-specific locale has been set.
+
 New in 0.9.1:
 * In the include file unicase.h, functions for case mapping of substrings have
   been added.

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+   for FUNCTION which will then trigger a compiler warning containing
+   the text of "literal string" anywhere that function is called, if
+   supported by the compiler.  If the compiler does not support this
+   feature, the macro expands to an unused extern declaration.
+
+   This macro is useful for marking a function as a potential
+   portability trap, with the intent that "literal string" include
+   instructions on the replacement function that should be used
+   instead.  However, one of the reasons that a function is a
+   portability trap is if it has the wrong signature.  Declaring
+   FUNCTION with a different signature in C is a compilation error, so
+   this macro must use the same type as any existing declaration so
+   that programs that avoid the problematic FUNCTION do not fail to
+   compile merely because they included a header that poisoned the
+   function.  But this implies that _GL_WARN_ON_USE is only safe to
+   use if FUNCTION is known to already have a declaration.  Use of
+   this macro implies that there must not be any other macro hiding
+   the declaration of FUNCTION; but undefining FUNCTION first is part
+   of the poisoning process anyway (although for symbols that are
+   provided only via a macro, the result is a compilation error rather
+   than a warning containing "literal string").  Also note that in
+   C++, it is only safe to use if FUNCTION has no overloads.
+
+   For an example, it is possible to poison 'getline' by:
+   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
+     [getline]) in configure.ac, which potentially defines
+     HAVE_RAW_DECL_GETLINE
+   - adding this code to a header that wraps the system <stdio.h>:
+     #undef getline
+     #if HAVE_RAW_DECL_GETLINE
+     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+       "not universally present; use the gnulib module getline");
+     #endif
+
+   It is not possible to directly poison global variables.  But it is
+   possible to write a wrapper accessor function, and poison that
+   (less common usage, like &environ, will cause a compilation error
+   rather than issue the nice warning, but the end result of informing
+   the developer about their portability problem is still achieved):
+   #if HAVE_RAW_DECL_ENVIRON
+   static inline char ***rpl_environ (void) { return &environ; }
+   _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
+   # undef environ
+   # define environ (*rpl_environ ())

+dnl Defines at most one of the macros USE_POSIX_THREADS, USE_SOLARIS_THREADS,
+dnl USE_PTH_THREADS, USE_WIN32_THREADS
+dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
+dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
+dnl libtool).
+dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
+dnl programs that really need multithread functionality. The difference
+dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
+dnl symbols, typically LIBTHREAD="" whereas LIBMULTITHREAD="-lpthread".
+dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
+dnl multithread-safe programs.

-	# Darwin 7.5 has nl_langinfo(CODESET), but sometimes its value is
-	# useless:
-	# - It returns the empty string when LANG is set to a locale of the
-	#   form ll_CC, although ll_CC/LC_CTYPE is a symlink to an UTF-8
-	#   LC_CTYPE file.
-	# - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
-	#   the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
-	# - The documentation says:
-	#     "... all code that calls BSD system routines should ensure
-	#      that the const *char parameters of these routines are in UTF-8
-	#      encoding. All BSD system functions expect their string
-	#      parameters to be in UTF-8 encoding and nothing else."
-	#   It also says
-	#     "An additional caveat is that string parameters for files,
-	#      paths, and other file-system entities must be in canonical
-	#      UTF-8. In a canonical UTF-8 Unicode string, all decomposable
-	#      characters are decomposed ..."
-	#   but this is not true: You can pass non-decomposed UTF-8 strings
-	#   to file system functions, and it is the OS which will convert
-	#   them to decomposed UTF-8 before accessing the file system.
-	# - The Apple Terminal application displays UTF-8 by default.
-	# - However, other applications are free to use different encodings:
-	#   - xterm uses ISO-8859-1 by default.
-	#   - TextEdit uses MacRoman by default.
-	# We prefer UTF-8 over decomposed UTF-8-MAC because one should
-	# minimize the use of decomposed Unicode. Unfortunately, through the
-	# Darwin file system, decomposed UTF-8 strings are leaked into user
-	# space nevertheless.
-	# Then there are also the locales with encodings other than US-ASCII
-	# and UTF-8. These locales can be occasionally useful to users (e.g.
-	# when grepping through ISO-8859-1 encoded text files), when all their
-	# file names are in US-ASCII.

+    #   LC_CTYPE file.
+    # - The environment variables LANG, LC_CTYPE, LC_ALL are not set by
+    #   the system; nl_langinfo(CODESET) returns "US-ASCII" in this case.
+    # - The documentation says:
+    #     "... all code that calls BSD system routines should ensure
+    #      that the const *char parameters of these routines are in UTF-8
+    #      encoding. All BSD system functions expect their string
+    #      parameters to be in UTF-8 encoding and nothing else."

+    #     "An additional caveat is that string parameters for files,
+    #      paths, and other file-system entities must be in canonical
+    #      UTF-8. In a canonical UTF-8 Unicode string, all decomposable
+    #      characters are decomposed ..."
+    #   but this is not true: You can pass non-decomposed UTF-8 strings
+    #   to file system functions, and it is the OS which will convert
+    #   them to decomposed UTF-8 before accessing the file system.
+    # - The Apple Terminal application displays UTF-8 by default.
+    # - However, other applications are free to use different encodings:
+    #   - xterm uses ISO-8859-1 by default.
+    #   - TextEdit uses MacRoman by default.
+    # We prefer UTF-8 over decomposed UTF-8-MAC because one should
+    # minimize the use of decomposed Unicode. Unfortunately, through the
+    # Darwin file system, decomposed UTF-8 strings are leaked into user
+    # space nevertheless.
+    # Then there are also the locales with encodings other than US-ASCII
+    # and UTF-8. These locales can be occasionally useful to users (e.g.

+         There are two possible approaches:
+           - Use iconv() and its return value.
+           - Use built-in knowledge about the possible encodings.
+         Given the low quality of implementation of iconv() on the systems that
+         lack mbrtowc(), we use the second approach.

+           - 8-bit encodings,
+           - EUC-JP, EUC-KR, GB2312, EUC-TW, BIG5, GB18030, SJIS,

+                            non-starter.  Btw, this check could also be

+                            a starter, no lookup will succeed.
+                         2. If the sortbuf has more than one character, check
+                            for each of these characters that are not "blocked"
+                            from the starter (i.e. have a ccc that is higher
+                            than the ccc of the previous character) whether it
+                            can be combined with the first character.
+                         3. If only one character is left in sortbuf, check
+                            whether it can be combined with the next character
+                            (also a starter).  */
