Speaking of register variables -- does anybody know what various C
compilers do when you don't declare variables as register, but there
are spare registers to use? From what I hear, neither ccom nor c2 are
smart enough to put local variables in registers when they are
available. It seems that it would be simple to just take the first few,
or even the most heavily used local variables that don't ever get &'d
and make them register...
