Hi,
On Linux/ia32, we require binutils 2.13.1 or later, which supports --32
which was added on 2000-12-20. This patch always passes --32 to assembler
on Linux/ia32 so that one can configure gcc as i686-pc-linux-gnu on
Linux/x86-64 to build/test Linux/ia32 gcc binaries. Tested on Linux/ia32
and Linux/x86-64. OK for trunk?
Thanks.
H.J.

Does this work for a mutli-arch compiled i686-linux-gnu compiler?
Thanks,

Yes. Such setup includes i386/linux64.h which redefines ASM_SPEC.

Well, OK then.
