(gdb) whatis sin
type = <text variable, no debug info>
(gdb) ptype sin
type = int ()

If the executable knows what kind of function sin is, then you would think that
GDB should be able to infer it from the executable.  ISTR this has come up
before (just with "print") but that you expressed no surprise then.
