Or you can pass -D__NO_INLINE__ on the command line. I'm of the
opinion that we should add that to GCC's specs for all glibc systems.
We already do something analogous during bootstrap for GCC itself to
disable all of the glibc string inlines. I don't see why the rest of
the world has to suffer through them when these things belong in the
compiler anyway.
