I've just added the stubs to the build system to make this really
trivial. All you need to do to add C source files is add the name of the
file to the *_c_source variable in the Files.am file the source dir. The
files will automagically be built.

We could do that. No hurry though. It costs us virtually nothing to
supply a full libm.a file since the sources files get built once and
then stuffed into both archives. If we wanted libm.a to be just an empty
place holder, we could just stuff a dummy.c file into the archive. In
the end, where the functions come from will be transparent to the end
user.

I have committed (to the autoconf branch) the patch to merge libm with
libc.
