only in Pentium4 and the future AMD x86-64 chips supports double precision
arithmetics too.
For i387 you need to use @option{-march=@var{cpu-type}}, @option{-msse} or
@option{-msse2} switches to enable SSE extensions and make this option
effective. For x86-64 compiler, these extensions are enabled by default.

The resulting code should be considerably faster in the majority of cases and avoid
the numerical instability problems of 387 code, but may break some existing
