[RP] register variable considered BAD

[Jonathan Walther]

-----BEGIN PGP SIGNED MESSAGE-----

Was reading the Gnu CC manual again.  It had this interesting
tidbit:  When the address of a variable is taken, it will never
be assigned a register.  EVER.  Even if the register keyword
was used.  I believe this is the case with the code in ratpoison
that does use register, and that would be why I noticed no
code difference in the generated object files when I compiled
with and without the register keyword.  If you want to actually
use registers, don't give the compiler hints, use inline assembly.
