C interface to Vax FPA

[utzoo!decvax!microsof!uw-beave!ubc-visi!woodham]

I'm looking for a C support for the Vax 11/780 floating point accelerator
(FPA).  In particular, I would like:

1.  Versions of the trigonometric functions (sin, cos, etc.) which use
    the POLY instruction

2.  A modification/interface to the C compiler so that the evaluation
    of a polynomial can be flagged and the appropriate machine code
    generated and/or interfaced to.

Before I go off and do these things myself, I thought I would ask.
