That is a possibility, but even in that case, the build shouldn't fail
with an obscure undefined symbol error at compile time. If we're going
to require either the winsup directory, or a cygwin installation, there
should be checks for these at configuration time. However, usually,
newlib doesn't handle header dependencies in this way.
newlib typically includes system-specific headers (like types.h) in the
newlib distribution (like in newlib/libc/sys/cygwin/include). Is there
any reason why this can't be done for the cygwin target?
