Preprocessed source triggering the ICE
Building a cross-compiler to i586-pc-mingw32 fails with an ICE while compiling
libgcc, or more precisely, libbid's bid128_div.c:
../../../../gcc/trunk/libgcc/config/libbid/bid128_div.c:1851:1: internal
compiler error: in inline_small_functions, at ipa-inline.c:1407
The cross-compiler is configured with: ../../gcc/trunk/configure
--prefix=/Users/fx/devel/mingw/cross --target=i586-pc-mingw32 --disable-werror
--with-gmp=/Users/fx/devel/gcc/deps-static/x86_64 --enable-languages=c,fortran
The backtrace of the ICE is:
#0 fancy_abort (file=0x100aae258 "../../../gcc/trunk/gcc/ipa-inline.c",
line=1407, function=0x100aae9a0 "inline_small_functions") at diagnostic.c:897

I attach the preprocessed source. The bug is triggered consistently at -O1 and
higher optimization. It can be reproduced simply with "cc1 -O bid128_div.i"
