=> You seem to be building the posix-BSP under Cygwin. Building this
is known to be problematic with certain Cygwin' versions and also is
known to be problematic at run-time in combination with certain
Win-version (I think, Joel could comment on this.)

I have never seen this before. Could you show us how you invoke
RTEMS's configure (Which configuration options you use)?

For the moment I would suspect,
* you might have set some environment variables which interfere with
RTEMS (In particular, make sure not to have set LIB, INCLUDES,
* you might not have a symlink called "cc.exe" pointing to gcc.exe
in $PATH.

I know there was a header conflict between RTEMS's unix/posix-BSP
and Cygwin's newlib between Cygwin 1.1.4 and 1.1.7, but I don't know
about the shape of Cygwin 1.1.8 and it's interaction with current
