Gcc does not implement sin/cos/atan/etc.  It relies on the host libraries to
provide these functions.  If you are using Linux, the host libraries are in the
glibc package, which you can get on any FSF mirror.  Glibc questions should be
directed to their mailing list, and not here.  For other systems, you need to
figure out who provides the library, and whether source is available.
