Constants that have the names of CPU registers are already defined
in OpenSolaris's sys/regset.h. This causes a warning as we try to
(re)define SS in ctype.c. So we just use another name.

I do not mind this _particular_ workaround per-se, but I have to wonder
what happens the next time some random other platform has "SP" defined in
a random header file.

If we are doing an workaround, how about doing it this way instead?
