[patch cygwin64]: Add and adjust some initial sources for x64 cygwin


Hi,

Hi,

the first part of required code-changes for upcoming cygwin x64 target.

ChangeLog

2013-03-22 Kai Tietz  <ktietz@redhat.com>

	* config/i386/cygwin-stdint.h: Add support for cygwin x64 target.
	* config/i386/t-cygwin-w64: New file.
	* config/i386/cygwin-w64.h: New file.
	* config/i386/cygwin.h (EXTRA_OS_CPP_BUILTINS): Extend
	and add support for x64-cygwin target.
	(CPP_SPEC): Likewise.
	(CXX_WRAP_SPEC_LIST): Undefine before define.
	(LIBGCJ_SONAME): Make name minor-build-version dependent.

Tested for i686-pc-cygwin, and x86_64-pc-cygwin.  Dave, please
especially a look to LIBGCJ_SONAME change. I think we should include
MAJOR_VERSION here, too. Ok for apply?

Regards,
Kai

Tested with i686-pc-cygwin, and x86_64-pc-cygwin.  I will apply
tomorrow, if there are no objections by other
Windows-target-maintainers.

Regards,
Kai
