"register" helps compilers in situations where normal
optimizations don't give satisfying results, e.g. to aid
in keeping often used variables or counters in registers
rather than on the stack. It can also help with inling
functions and can speed up parameter passing.

GCC is one such modern compiler that does care, not sure
about MSVC++. IBM's OS/2 compilers did (last time
I looked some 5 years ago ;).
