I have already built a linux hosted powerpc-eabi targeted cross-compiler. I
have also built a cygwin hosted powerpc-eabi targeted cross-compiler (this
was built on a linux machine following Mumit's howto - thanks). I previously
built the linux-cygwin cross-compiler using the dev-cygwin sources. I assume
that I don't need the "src-by-top-dir" for this case.

This is the bit that I think I'm missing. Apparently this is part of newer
cygwin releases/snapshots which is what I was trying to find, but I got
confused between the dev-cygwin sources and other cygwin sources. OK, so I
will get the libtermcap.tar.bz2 package and see what happens. BTW. Is this
package a cygwin only package or is it a generic package for all posix
compliant APIs ?
Thanks,
Brendan Simon.
