Unfortunately, the "search <libm.a>" construct is something you
want your code-generator to do -- as you said, it becomes
a loader directive.  Currently, though, #-etc. are done by the
C preprocessor...

A more general concern though is that we wouldn't want the C
language have to know anything about its environment... even
though this is minimally more difficult than #include files.
I'd really love the idea -- in fact, some other Dec-10 style
loader directives would be nice, such as a #require (which says,
put this object in there, regardless whether there are resolved
external symbols in it) lines.  [This'd be nice for libraries that
wanted to have their own external variable library elements which
didn't have any required routines in them.  I often want to do this,
but have to hack a bit to do it.]  Still, this belongs in the
environment, not the language.
