Hi,

this patch replaces use of _WIN64 by __x86_64__ so mingw x64 and
cygwin x64 version can share same source.

ChangeLog

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

	* config/i386/cygwin.S: Replace use of _WIN64 by __x86_64__.

Tested for x86_64-w64-mingw32, x86_64-pc-cygwin, and i686-w64-mingw32.
 I will apply tomorrow if there
are no objections by other Windows-maintainers.

Regards,
Kai
