I agree.  It's just that the util I'm looking at is GNU cpp, which DOES have
a cygwin specific port but doesn't seem to deal with the CRLF problem.  So
we've got the situation that, for whatever reason, it doesn't look like all
the Cygwin changes were rolled into the public branch which is the puzzle.
I'm wondering if there is some reason why but I'm agreeing with you and I
think I might just hack the preprocessor to properly deal with the '\r'.
Probably the most portable way.

cheers,

Kris
