There is an option for floating point code generation.  I have this
option turned off because the playstation does not have floating point
support.  Some of the demos use floating point math, so I presume that
the floating point is emulated by the GNU compilers.  The Metrowerks
compiler appears to be issuing floating point instructions regardless of
the fp code gen option.

In addition, when a floating point number is converted to an integer a
call is made to an external function "__cvt_dfp2unsigned".  This
function does not exist in the play station library.

What gives?
