Looking at the code, I wonder if we already have folks not using
spinlocks, and not even knowing it. I don't think problem reports will
be limited to new platforms.

Sure, and I am not pushing the patch. I am just saying it would have
been ideal a few weeks ago --- I am not sure if we are worse off with or
I just learned from Larry that Unixware defines intel as i386, not
__i386 or __i386__, at least of the native SCO compiler that he uses.
What the code used to do is define NEED_I386_TAS_ASM unconditionally on
some platforms (negating the need to test for a compiler symbol) or test
for each platform compiler symbol (and not test all possible ways it
could be specified), like FreeBSD did. That's why things are so messy.
I am going to test for __cpu, __cpu__, and cpu on non-gcc compiler for
consistency. It is only done in one place in the patch, so that should
