It is unlikely g77 will ever support this feature,
as doing it properly requires complete emulation of
a target computer's floating-point facilities when
building g77 as a cross-compiler.
But, if the gcc back end is enhanced to provide
such a facility, g77 will likely use that facility
in implementing this feature soon afterwards.
