Ok fixed. (variable is #ifdef XLOG)

FreeBSD always reports i386. -O2 is not appropriate for arches other
than i386 because of potential gcc bugs.

Yes, possible gcc bugs under alpha.

Yes, can you point to at the general location of that code? I'd
like to see if it's a FreeBSD bug, FreeBSD-alpha bug, Postgresql
bug or Postgresql-alpha bug or any combination thereof. :)
I've updated the patch again, I've changed the CFLAGS to be -O on
everything but i386 and #ifdef'd the variable based on XLOG.
I've also run regression on i386 since I've posted the patch and
the results are consistant with i386 without my patch.
Question, how much of an impact is using test and set over using
system semaphores? Would it be worth it to patch 7.0.x for alpha
and using hardware spinlocks rather than kernel mutexes?
I'd like to give my FreeBSD boxes running 7.0.3 a little boost if
