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 */
