+/* Filename support.
+   ISSLASH(C)                  tests whether C is a directory separator
+                               character.
+   HAS_DEVICE(Filename)        tests whether Filename contains a device
+                               specification.
+   FILE_SYSTEM_PREFIX_LEN(Filename)  length of the device specification
+                                     at the beginning of Filename,
+                                     index of the part consisting of
+                                     alternating components and slashes.
+   FILE_SYSTEM_DRIVE_PREFIX_CAN_BE_RELATIVE
+                               1 when a non-empty device specification
+                               can be followed by an empty or relative
+                               part,
+                               0 when a non-empty device specification
+                               must be followed by a slash,
+                               0 when device specification don't exist.
+   IS_ABSOLUTE_FILE_NAME(Filename)
+                               tests whether Filename is independent of
+                               any notion of "current directory".
+   IS_RELATIVE_FILE_NAME(Filename)
+                               tests whether Filename may be concatenated
+                               to a directory filename.
+   Note: On native Windows, OS/2, DOS, "c:" is neither an absolute nor a
+   relative file name!
+   IS_FILE_NAME_WITH_DIR(Filename)  tests whether Filename contains a device
+                                    or directory specification.
