FWIW, this patch works fine on my -current pmax.  I'll try it on my
1.3.3 machine soon too.

I'm tempted to say it shouldn't depend on the object file format.  That
said, Solaris 2.6/sparc (an ELF system) returns the "corrent" (ie,
`libc_sin 0' behaviour).

I'd say go with it, and I'll test it under 1.3.3 and send a pull-up.
