Update.
2003-03-07 Ulrich Drepper <drepper@redhat.com> * init.c (__static_tls_align_m1): Renamed from __static_tls_align. (__pthread_initialize_minimal_internal): Change initialization of __static_tls_align_m1 appropriately. * pthreadP.h (__static_tls_align_m1): Renamed from __static_tls_align. * allocatestack.c (allocate_stack): Use __static_tls_align_m1 instead of __static_tls_align-1.
