Enable Java on Cygwin-64

Browse Source 
Currently it is not possible to build GCC's libjava support on Cygwin-64.

This patch fixes the current build-problems on Cygwin-64 and the most
fundamental bugs on that platform.

Note you must still add --enable-threads=posix to successfully build the
java language support.
