I plan to change BIGGEST_ALIGNMENT back to 64 bits on the 32 branch today
assuming that testing is successful. The main branch was changed yesterday.
This affects the alignment of long doubles under hpux and possibly the
alignment of __atomic_lock_t types parisc-linux linux.
I have been testing revised glibc locking code. It only requires integer
alignment for __atomic_lock_t types. I am convinced this is the
correct solution. The __attribute__ ((aligned(16))) doesn't always
do what you want. Specifically, it doesn't work for stack locals, or
There is still one gcc pthread test failure (pthread6) under investigation.

I had a lot of trouble testing the glibc fix until I realized you have
to rebuild gcc after the change. It depends on the specifics of the lock
