It was the easiest way to test the functions in pystrcmp. Linux doesn't
have stricmp but it also doesn't require the additional code to mangle
1.#INF into inf.

See Tim's answer.
Pickles and other C programs aren't an issue. Internally NaNs and INFs
are represented with a special bit pattern (all bits of the exponent are
set). As long as users don't use str() or repr() on floats it still
works. The pickle module uses struct.

I missed the spot, thanks.
