Um, sure you can rename the variable in libbfd.c, but you can't rename
all static variables called "mask" in all the programs in the world
(including those not written yet). The compiler _mustn't_ fail to
generate working code from something just because it contains a
variable called "mask", that would violate the C standard.
What happens if you call a static variable "d0"? I suppose the same
thing should happen to static variables called "mask". Anyway it has
to work. Both "mask" and "d0" are valid variable names.
