The failure noted in PR 20553 is now fixed on hppa64-hp-hpux11.  However,
we are still left with the followin minor regression on hppa2.0w-hp-hpux11:

FAIL: gcc.c-torture/compile/20011119-1.c  -O0  (test for excess errors)
FAIL: gcc.c-torture/compile/20011119-1.c  -O1  (test for excess errors)

FAIL: gcc.c-torture/compile/981001-2.c  -Os  (test for excess errors)

These now fail because of the warning:

Executing on host: /mnt/gnu/gcc-3.3/objdir/gcc/xgcc -B/mnt/gnu/gcc-3.3/objdir/gc
c/   -O3 -g  -w -c  -o 981001-2.o /mnt/gnu/gcc-3.3/gcc/gcc/testsuite/gcc.c-tortu
re/compile/981001-2.c    (timeout = 300)
/mnt/gnu/gcc-3.3/gcc/gcc/testsuite/gcc.c-torture/compile/981001-2.c:12: error: a
lias definitions not supported in this configuration

These used to pass because the alias was output together with the definition.
