Hi, currently it is not possible to build GCC's libjava support on Cygwin-64. The attached patch fixes the current build-problems and the most fundamental bugs on that platform.
Note you must still add --enable-threads=posix to successfully build the
java language support.
Boot-Strapped on Cygwin-32 and Cygwin-64.
OK for trunk and 4.9.1?
Thanks
Bernd.
