Try adding -fomit-frame-pointer; that will free up a register, which
is pretty important on register-starved architectures such as x86 and
x86_64.   (depending on your -O<n> level, it might already be turned on
though)

According to the manpage, that's already the default as of GCC V4.6.   I'm currently doing some tests with GCC 4.7.0, the latest release.

  Cool.   But...the default?   With no frame pointers, debugging is pretty
difficult.   I assume it's only enabled with -O[n], and disabled with
-g[xxx]?
