  It seems pretty unlikely that it would have any hardcoded path at all, let
alone one under /cygdrive, and there's certainly no matching string in the
dvips executable.  It's more likely coming in from somewhere else.  Have you
remembered to update any environment variables such as $TEMP or $HOME or
whatever that might still have /cygdrive paths in them?

  No, or at any rate there shouldn't be.  Anything that needs to know that
prefix should be deriving it from /etc/mtab.

  (Hmmph, on a side-note, it looks like we need to tweak our mtab format to be
unambigouously machine parseable wrt. paths containing spaces.)

  Yeah, but you've probably misanalysed what's going on there.

  Nope.

  You can mkdir a real "cygdrive" dir under "/" and place soft-links "c" ->
"/c", "d" -> "/d" as needed.  (This avoids the horrors of a recursive file
system that would arise if you created a softlink in "/" called "cygdrive"
pointing back to "/".)

    cheers,
