Building from today's cvs in all cases with --enable-threads=posix, and
with -DAO_USE_PTHREAD_DEFS on AIX, IRIX, Tru64 and Solaris 10/x86 (older
sun studio can't build the inline asm).

On AIX 5.1 every test fails like this:
FAIL: hugetest
sem_init failed
/bin/sh: 1335468 IOT/Abort trap(coredump)

AIX 5.3, 6.1 and 7.1 pass all tests.

initsecondarythread crashes on all HP-UX and on Tru64.
On ia64-hp-hpux11.31 the crash is here:
SEGV_MAPERR - Address not mapped to object
#0  0x60000000ca58ae20:0 in GC_mark_from (mark_stack_top=0x40058040, 
    mark_stack=0x40058000, mark_stack_limit=0x40060000) at mark.c:820
    820               deferred = *(word *)limit;
(gdb) p limit
$2 = 0x777b50b8 <Address 0x777b50b8 out of bounds>

Solaris 7 and 8 , IRIX 6.5, AIX 5.2, and sometimes on HP-UX gctest hangs

Also, strangely, when building with --disable-threads, Solaris 10/x86
gctest crashes with a segv, every other one of our platforms passes all
tests. segv is in test.c at
    if (SEXPR_TO_INT(car(car(list))) != low) {

Let me know if you need more info on any of these.
