Hmm.  There does not seem to be any support for non-gcc Solaris/86 in
src/include/storage/s_lock.h.  I am not sure why not, since we do have
a src/backend/port/tas/solaris_i386.s file, which should work as an
external implementation of TAS().  Perhaps it got lost in the recent
reorganization of the spinlock code.  Can you test a suitable addition?
It probably doesn't need to be any more complicated than the entry
for old SunOS:

#if defined(sun3)
#define HAS_TEST_AND_SET

typedef unsigned char slock_t;
#endif

but I'm unsure what's an appropriate #if to recognize Solaris/x86.
