[PATCH] Work around for current Cygwin-32 Build problems

[Bernd Edlinger]

Hi,

due to a defect in the currently available binutils-2.24 and earlier, it is not 
possible
to boot-strap GCC 4.9.0 and trunk with certain widely used configurations for 
Cygwin-32 environment.
See PR 60830 for details.

Boot-Strapped on x86-64-cygwin and i686-pc-cygwin with binutils-2.24.

OK for trunk and 4.9 branch?


Thanks
Bernd.

        * config/i386/cygming-crtbegin.c (__register_frame_info,
        __deregister_frame_info, _Jv_RegisterClasses): Compile weak default
        functions only for 64-bit systems, when absolutely necessary.
