description:
I got a report about this not compiling on mips64.  While I could
not repeat the problem and while this should not be used at all on
mips64, the real fix is a little diablo in the details.  So hack
around it for now (yes, it results in only half of the locks being
used on 64bit platforms.  no biggie for a hack).
