A better workaround than disabling spinlocks at all is to compile
s_lock.c with -fno-unit-at-a-time (this is the default in gcc 4 and
breaks it; that was the reason why it worked with gcc 3.3).
However, Thiemo Seufer dealt with this and created a proper tas()
function for PostgreSQL on mips, which also works with gcc 4. Of
course this is much better, so I applied his patch in Debian.
I attach the patch. Do you consider applying it upstream?
Thanks and have a nice weekend,
Martin
