or:
../glibc-2.2.2/configure --verbose --build=m68k-unknown-linux --prefix=/gnu
creating cache ./config.cache
checking host system type... i586-pc-cygwin
checking sysdep dirs... configure: error: Operating system cygwin is not
supported.

Do I need a different glibc or can I patch the configure files to accept
cygwin?
