Speaking of gcc-4.2.1, Ted Jordan writes on 20090401:
The generated libtool for building libstdc++ adds the -nostdlib option to the
g++ command for linking but doesn't add -lgcc. This causes a "hidden symbol"
error when linking against the libstdc++ shared object. This patch adds gcc
to the list of libraries linked against when linking libstdc++.

fnstsw stores 16bit into %ax. The upper 16bit of %eax is unchanged.

The new assembler (binutils-2.18.50.0.4 and up) will disallow "fnstsw %eax".
