Well, that's the usual problem with the math libs; they want to be nice and
output some error codes if something goes wrong.
Either "implement" fputs(), and provide a fake stderr (you're the only one
who will ever see it, as there are no calls that could use it in kernel
space), or get the source of the math lib and just rip the code you need,
rewriting the offendning error output code.
IIRC, I've also heard something about some versions of the math libs not
doing error output directly, thus being usable in kernel space right away.
Don't remember the details, and I'm not up to date as I haven't done serious
maths in kernel space for a good while...
