Hmm...  I noticed this problem yesterday from less.  I then check the less
version and installed the 4.0 version I had built --with-ncurses and my
problems went away.

I don't yet know what's causing this either.  When I was installing 1.1.4 over
my existing 1.1.3 I did tar -zxvf /tmp/latest/cygwin/cygwin...gz from the /
directory, then exited all cygwin and replaced the cygwin1.dll with the one
from the tarball and had an unusable system.  No process would start. 
Installing with setup seemed to correct this problem but now I'm having other
side affects.

Adding -lm and -lc to the link process are definite problems.  I haven't
reviewed your sample code yet but rest assured you don't want to `gcc -o foo
foo.c -lc -lm'.  As for using gcc and cygwin1.1.4, I've built the cygwin
runtime several times without these problems while using Cygwin1.1.4 product
itself.
