Update.
2003-09-23 Ulrich Drepper <drepper@redhat.com>
* sysdeps/unix/sysv/linux/powerpc/powerpc32/Versions [libc]
(GLIBC_2.3.3): Add setcontext, getcontext, swapcontext, and
makecontext.
* sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h: Correct change
for include Altivec support for PPC32. It was not compatible.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/ucontext_i.h: Adjust
offsets for ucontext_t change.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/getcontext.S: Adjust
for ucontext_t change. Add compatibility code.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/makecontext.S: Likewise.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/setcontext.S: Likewise.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext.S: Likewise.
Patch by Paul Mackerras <paulus@samba.org>.
