Fixed lots of warnings from gcc-2.7.x about "left-hand operand of
comma expression has no effect" in the MAKE_SET() macro. This also
fixes compiling with -O3 (which removes static functions unless
there is a suitable reference to them). Declaring all the static
symbols as __unused would also fix the warning, but would be bogus
(they are used) and wouldn't fix -O3. However, the dummy pointers
for the references waste about 1.5K text and 20K symbol space for
GENERIC. This wastage hasn't changed - the dummy pointers are just
nonzero now.
