Sounds to me like all of your text files (.h's, &tc.) were CR/LF translated
when you originally untarred them. This can happen if you (1) use WinZip or
some other windows-centric program to untar.gz the archives, such as the
egcs tar.gz file (2) you untar.gz'ed using cygwin-based tar, but the
destination location was a text mount, so the low-level file routines did a
CR/LF conversion for you. I think the easiest way to fix this, without
disturbing a setup that already is properly configured, is to get rmhatm
from ftp://insomnia.be/johanvg/rmhatm-0.2.tar.gz
Be warned: I haven't tried this program myself, but it is a Perl program
that will
_recursively_ (!! careful !!) descend into your directory structure, and
convert all text files from DOS/MAC to Unix format. (Of course, you'll have
to mount everything binary _before_ running the conversion.
The other way to fix it is to mount everything binary, and then reinstall
egcs from the original tar.gz file.

I dunno about all this stuff.
