When I build gcc 4.8 with mingw-w64 trunk:
${GCC_SRC_ROOT}/configure \
--prefix=${SYS_ROOT} \
--with-sysroot=${SYS_ROOT} \
--build=${BUILD_TRIPLET} --host=${BUILD_TRIPLET}
--target=${TARGET_TRIPLET} \
--enable-targets=all --disable-nls \
--enable-checking=release --enable-languages=c,c++,fortran
If TARGET_TRIPLET is x86_64-w64-mingw32, the building works good.
When TARGET_TRIPLET is i686-w64-mingw32, I got errors:

When I add '--enable-sjlj-exceptions', the building works good. But
64bit use sjlj not seh. Can I let 32bit use sjlj and 64 bit use seh
when default target is 32bit ?
