I think this is more likely a C compiler issue than an ABI issue.  If
only the C compiler promotes float to double, then the conversion has to
happen in the C front end.  This is the case with the old K&R C
requirement of promoting floats to doubles, which was implemented in the
C front end.

It would be good to check this though.  If the SCO compiler supports
Fortran, Java, Ada, or C++, check to see if any of the other languages
need this conversion.  My expectation is that they do not.
