The function in question is

void helper_flds_FT0(uint32_t val)
{
    union {
        float32 f;
        uint32_t i;
    } u;
    u.i = val;
    FT0 = float32_to_floatx80(u.f, &env->fp_status);
}

and the line# listed is the closing brace.

>How-To-Repeat:

	Build qemu0 on i386 netbsd-6 machine.

	I tried -Os, O, O0 with a hacks.mk file, but it didn't make a
	difference.

>Fix:
	None here.

 Currently, (if you pick up qemu0), it will say:

 /usr/pkgsrc/emulators/qemu0/work/qemu-0.15.1/target-i386/op_helper.c: In function 'helper_flds_FT0':

 Note that the 'confused by earlier errors' is at the same line
 as your internal compiler error.

 As for why this errors, there appears to be
 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=62144

 Latest GCC trunk still gives this error.
