Hi,
I've seen various posts about the "fnstsw" compile bug - always with a reply stating --disable-asm or --enable-asm=no fixes it.

While that does fix it, it also disables some optimizations -- there is a better fix.

The problem is caused by the use of the asm statement

fnstsw %eax

That used to work with old versions of binutils, current binutils versions (correctly) reject it as invalid because it uses a 16 bit operation on a 32 bit register.

The correct fix is to work on the 16 bit version of the register instead:

fnstsw %ax

I'm attaching a patch that fixes this.

No reason to not apply it.
It does mean that we should output 4.4 at least, maybe 4.2.3 (with just minor fixes like this) as well.
