I'm actually quite certain that what you wrote would help. The issue is
that cccp.c (the gcc preprocessor) does not do that and, as near as I can
tell from the FAQ, shouldn't need to. That, however, is where I might be
wrong. I'm wondering if the cpp shipped with Cygwin has been patched so
that it does explicitly open files as text. If that's the case, then that
might explain why I'm seeing different behaviour.
Aha! I just copied dosfile.c to a text mode partition and it works with our
preprocessor. That implies that there must be some buggery in the Cygwin
version of cpp.exe. I noticed that the version of gcc shipped with cygwin
is 2.95.3-5. Is the '-5' some form of Cygwin specific patch with some
assorted magic in it? Perhaps someone on this list would know.
cheers,
Kris
