Try the procedure here and let's see what's up...

http://www.rtems.com/onlinedocs/releases/rtemsdocs-4.6.1/share/rtems/html/started/started00056.html

DO the "-c" test there and then try to do a full compile/link with
this:

int main() { return 0; }

configure is trying something like the above when it fails.  You can
add a -v to see the details.

Do you have the Cygwin filesystem mounts in binary mode?
