You should trust Eli a bit more...

You're right that some version of libm was merged into libc (around
the time of DJGPP 2.0, IIRC). *But* there is another, much more solid
libm part of the DJGPP installation, and *that's* the one you should
be looking at if you're doing any serious maths work, including any
situation where you have to deal with NaN's. Go figure.
