	-msoft-float converts all floating point computations to
emulation, as opposed to only using FPRs for floating point statements.
Please review the original problem and the documentation for
"-msoft-float" for more information.

	Such a patch would not be limited to the target-specific portion
of the compiler, which is what all of the previous patches have limited
themselves to.
