-/* Function calling conventions.
- * =============================
- * Normally it is not necessary to specify to the compiler how to call
- * a function - it just does it - however on x86 systems derived from
- * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
- * and some others) there are multiple ways to call a function and the
- * default can be changed on the compiler command line. For this reason
- * libpng specifies the calling convention of every exported function and
- * every function called via a user supplied function pointer. This is
- * done in this file by defining the following macros:
- *
- * PNGAPI Calling convention for exported functions.
- * PNGCBAPI Calling convention for user provided (callback) functions.
- * PNGCAPI Calling convention used by the ANSI-C library (required
- * for longjmp callbacks and sometimes used internally to
- * specify the calling convention for zlib).
- *
- * These macros should never be overridden. If it is necessary to
- * change calling convention in a private build this can be done
- * by setting PNG_API_RULE (which defaults to 0) to one of the values
- * below to select the correct 'API' variants.
- *
- * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
- * This is correct in every known environment.
- * PNG_API_RULE=1 Use the operating system convention for PNGAPI and
- * the 'C' calling convention (from PNGCAPI) for
- * callbacks (PNGCBAPI). This is no longer required
- * in any known environment - if it has to be used
- * please post an explanation of the problem to the
- * libpng mailing list.
- *
- * These cases only differ if the operating system does not use the C
- * calling convention, at present this just means the above cases
- * (x86 DOS/Windows sytems) and, even then, this does not apply to
- * Cygwin running on those systems.
- *
- * Note that the value must be defined in pnglibconf.h so that what
- * the application uses to call the library matches the conventions
- * set when building the library.
- */
-
-/* Symbol export
- * =============
- * When building a shared library it is almost always necessary to tell
- * the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
- * is used to mark the symbols. On some systems these symbols can be
- * extracted at link time and need no special processing by the compiler,
- * on other systems the symbols are flagged by the compiler and just
- * the declaration requires a special tag applied (unfortunately) in a
- * compiler dependent way. Some systems can do either.
- *
- * A small number of older systems also require a symbol from a DLL to
- * be flagged to the program that calls it. This is a problem because
- * we do not know in the header file included by application code that
- * the symbol will come from a shared library, as opposed to a statically
- * linked one. For this reason the application must tell us by setting
- * the magic flag PNG_USE_DLL to turn on the special processing before
- * it includes png.h.
- *
- * Four additional macros are used to make this happen:
- *
- * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
- * the build or imported if PNG_USE_DLL is set - compiler
- * and system specific.
- *
- * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
- * 'type', compiler specific.
- *
- * PNG_DLL_EXPORT Set to the magic to use during a libpng build to
- * make a symbol exported from the DLL. Not used in the
- * public header files; see pngpriv.h for how it is used
- * in the libpng build.
- *
- * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
- * from a DLL - used to define PNG_IMPEXP when
- * PNG_USE_DLL is set.
- */
-
-/* System specific discovery.
- * ==========================
- * This code is used at build time to find PNG_IMPEXP, the API settings
- * and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL
- * import processing is possible. On Windows systems it also sets
- * compiler-specific macros to the values required to change the calling
