Where the system.h header of today's snapshot changes the definition

What I see in the current gcc/system.h is:

#ifndef PATH_SEPARATOR
#define PATH_SEPARATOR ':'
#endif

Can you explain the issue you are seeing in more detail?

Ian
gcc/system.h  sets PATH_SEPARATOR
#ifndef PATH_SEPARATOR
#define PATH_SEPARATOR ':'
#endif

include/filenames.h changes PATH_SEPARATOR:
#if defined(__MSDOS__) || defined(_WIN32) || defined(__OS2__) || defined (__CYGW
IN__)
# ifndef HAVE_DOS_BASED_FILE_SYSTEM
# define HAVE_DOS_BASED_FILE_SYSTEM 1
# endif
# undef PATH_SEPARATOR // added to enable build
# define PATH_SEPARATOR ';'
# define HAS_DRIVE_SPEC(f) HAS_DOS_DRIVE_SPEC (f)
# define IS_DIR_SEPARATOR(c) IS_DOS_DIR_SEPARATOR (c)
# define IS_ABSOLUTE_PATH(f) IS_DOS_ABSOLUTE_PATH (f)
#else /* not DOSish */
