strict aliasing problem in GNU Mach

Among lot of warning, while compiling GNU Mach with recent gcc's we
get lot of warnings related to strict aliasing optimization. This
might lead the compiler into producing incorrect code.

I personally think that instead of modifying GNU Mach's code (and
limit our cast usage) we  can simply get rid of this invasive
optimization by adding to CFLAGS -fno-strict-aliasing.

What do you think?


It was a type of people I did not know, I found them very strange and
they did not inspire confidence at all. Later I learned that I had been
introduced to electronic engineers.
