  Heh, yes, I know.  I'm the maintainer of the cygwin gcc packages.

  We used to have a gpc build and then it got dropped and when I took over gcc
maintainership I threw together a newer version.  It's entirely possible I did
something wrong, although it passes most of the gpc testsuite:

  No, I was guessing wrongly about the purpose of the crt.* files in
.../units/.  I don't know what the problem is, so please do report back what
you find out from the pascal list and if there's a bug in the way I ported the
newer gpc to gcc-3.3.3, I'll fix it.

    cheers,
