[PATCH] get rid of all "register" storage class specifiers
Robert P. J. Day
rpjday at mindspring.com
Sat Jul 1 12:51:23 UTC 2006
i've suggested this before, and no one seemed to have any major
objections. note the number of register specifiers in msh.c. yeesh.
in any event, i can commit this later if no one has a problem with it.
