For Cygwin, people should be using POSIX pathnames only to avoid these
misfeatures (note that I'm not calling it a bug ;-). For Mingw, it should
work as is.

For egcs-1.2, now there's DIR_SEPARATOR ('/') and DIR_SEPARATOR_2 ('\\'), 
and we check for both. I just tested this and I get the same output 
locations for both '\\' and '/' cases. Here's the new macro that checks
for dir separator.

  /* Define IS_DIR_SEPARATOR.  */
  #ifndef DIR_SEPARATOR_2
  # define IS_DIR_SEPARATOR(ch) ((ch) == DIR_SEPARATOR)
  #else /* DIR_SEPARATOR_2 */
  # define IS_DIR_SEPARATOR(ch) \
	  (((ch) == DIR_SEPARATOR) || ((ch) == DIR_SEPARATOR_2))
  #endif /* DIR_SEPARATOR_2 */
