libm is a subcomponent of the final cygwin1.dll, which merges several
such components.  There's also libpthread, libc, libserver, libutil, the
malloc code, the startup code (etc.) all of which are combined to make
cygwin1.dll.  As far as I know this is only done for link efficiency, as
these sub-libs are never distributed and probably don't work as
standalone libraries.
