GCC was configured with

BOOT_CFLAGS="-O3 -mfpmath=sse -msse2 -funroll-loops -ffast-math"
RUNTESTFLAGS="--target_board='unix'" /export/gnu/import/git/gcc/configure
--enable-clocale=gnu --with-system-zlib --with-demangler-in-ld
--enable-languages=c,c++,fortran i686-linux --prefix=/usr/gcc-4.8.0
--with-local-prefix=/usr/local --enable-gnu-indirect-function
--with-build-config=bootstrap-lto --with-fpmath=sse

I also got

/export/gnu/import/git/gcc/libiberty/simple-object-mach-o.c: In function
\u2018simple_object_mach_o_find_sections\u2019:
/export/gnu/import/git/gcc/libiberty/simple-object-mach-o.c:653:37: error:

[-Werror=maybe-uninitialized]
     secoffset = wrapper_sect_offset + subsect_offset;
