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.
boehm-gc/ChangeLog:
2014-05-13 Bernd Edlinger <bernd.edlinger@hotmail.de>
Fix current cygwin-64 build problems.
* include/gc_config_macros.h (GC_PTHREADS): Use __CYGWIN__ instead
of __CYGWIN32__ here.
* win32_threads.c (GC_push_all_stacks): Push all X86_64 registers.
(GC_get_thread_stack_base): Get the stack base for X86_64.

* src/x86/ffi.c: Add if defined(__CYGWIN__).
* src/x86/win64.S (ffi_closure_win64, ffi_call_win64): Added
handling for FFI_TYPE_UINT64, FFI_TYPE_POINTER and FFI_TYPE_INT.
Added SEH information. Fixed formatting.
