g77 doesn't yet support the "degree" forms of trig intrinsics that
some other compilers (like Digital's, and, I guess, Sun's) do. It'd
be nice to support them someday -- patches to do so are welcome!
Note that these intrinsics are not standard AFAIK -- certainly they're
not in F77 or F90, but I gather they're also not in F95, and don't
recall seeing them on the list of things for F2K to support.
But I assume they can be quite useful.
