Reproducible with a 4.9 cross to x86_64-w64-mingw32.  Started with r200349, but
that may simply have triggered a latent problem.

The reduced test case also ICEs 4.8-20130704, 4.7-20130706, and 4.6-20130405
(haven't checked older versions yet).

Hmm, I tried to reproduce this case with testcase:

extern unsigned int __builtin_ia32_crc32si (unsigned int, unsigned int);
#pragma GCC target("sse4.2")

and I don't get this ICE.  I might do here something wrong, but I can't
reproduce it.

If your compiler default target support sse4.2, then you can't reproduce it:

i686-w64-mingw32-gcc -march=corei7 pr57848.c

But when you use target which do not support sse4.2, then the internal compiler
error occurred:

$ i686-w64-mingw32-gcc -c -march=core2 pr57848.c

Yes,it helps, 64 bit gcc 4.9 build fine. but 32 bit failed with lots of
'conflicting types' errors, this maybe another story.

This has to be fixed in mingw-w64-headers. I will attach a draft of the patch
for testing.

When I use this 64 bit gcc 4.9 cross compiler to generate the native compiler,
I got the error:

Thanks Jacek for providing this work-a-round here,  but I would like to ask
Dongsheng not to hi-jack this bug for another one. See for Dongshengs
subject-change the existing PR/56038.
And well, this bug can be work-a-rounded by mingw-w64, but finally solved it
can be only on gcc-side.

The patch worked for me, but now I'm getting a new error that looks like Bug
47052 accept the proposed fix doesn't work because is says DW2 isn't suppored
on 64-bit yet.

I can get around this if I change "--enable-languages=c,c++" to
"--enable-languages=c", but I don't really want to, cause then I don't have a
c++ compiler.
