Hey thanks. I recognised that the problem was in a system level C
file, when I was trying to compile a Pascal file. The thing is that
gpc is a Pascal compiler that is linked against the gcc backend. The
GNU Pascal page
(http://directory.fsf.org/devel/prog/pascal/GNUPascal.html) states
that it implements ISO Pascal, Borland Pascal 7.0, and parts of other
Pascal standards or de-facto standards.
I tried removing the call to Use Crt, and have other errors. I am
going to ask my question on the GNU-Pascal mailing list, since you do
not seem to feel that this is a Cygwin issue, but a) since gpc speaks
Borland, I would assume that it is not being messed up with the Uses
Crt, and b) since gpc comes as a part of the Cygwin install, and since
I installed it using the Cygwin Setup executable, I would think that
there should be no problem with it finding the correct object file,
but in this case it didn't. Why would gpc start a gcc compile of the
crtc.c file? I don't know that answer to that question.
Any other takes on this would be appreciated. As I said, I am going
to chat on the GNU-Pascal list, but if anyone was seen this or has an
idea, I would be very appreciative.
