Coming from the C-shore of the language ocean, that does indeed strike
me as something that just doesn't happen very often, if ever, under C.

I probably should have used "interesting" instead of "odd".  After I 
looked at the problem more, I decided it was just lameness in the native
assembler.   I've filed a problem report with SCO on it.

It's sort of a curse on OpenServer becuase we don't support GAS very
well at all on this target.    When I start thinking about the subset
of OpenServer Fortran users that are building with -fpic, I just can't
get too worked up about making it work right for the COFF case o
additionally.

If there isn't an easy way to make the machine-dependent code not
emit this construct, I suggest we just punt on it.
