 It's not clear what the rationale was as the origin was lost between 
commit 1730ec6b1848 and commit 252b5132c75, which we have no history for 
other than:

	* ldfile.c (slash): Set to backslash if _WIN32 but not
	__CYGWIN32__.
	(ldfile_open_file_search): If __MSDOS__ or _WIN32, accept a
	leading backslash or a leading x: as an absolute path.
	(ldfile_find_command_file): Use slash rather than / when
	generating name to try.
	* lexsup.c (PATH_SEPARATOR): Define.
	(set_default_dirlist): Use PATH_SEPARATOR rather than ':'.
