@item --enable-host-shared
Specify that the @emph{host} code should be built into position-independent
machine code (with -fPIC), allowing it to be used within shared libraries,
but yielding a slightly slower compiler.
Currently this option is only of use to people developing GCC itself.
Contrast with @option{--enable-shared}, which affects @emph{target}
