I turned off HAVE_GAS_WEAK in auto-host.h and rebuilt.  __builtin_delete
is no longer unsatisfied.  However, I am still left with the following
unsatisfied symbols when linking the hounddog test:

spawn /xxx/gnu/gcc-2.96/objdir/gcc/xgcc -B/xxx/gnu/gcc-2.96/objdir/gcc/ ../../../../libio/testsuite/../tests/hounddog.cc -O3 -I.. -I../../../../libio/testsuite/.. -nostdinc++ -I/xxx/gnu/gcc-2.96/libstdc++ -I/xxx/gnu/gcc-2.96/libstdc++/stl -L/xxx/gnu/gcc-2.96/objdir/hppa1.1-hp-hpux10.20/threads/libstdc++ -L/xxx/gnu/gcc-2.96/objdir/hppa1.1-hp-hpux10.20/threads/libiberty -L/xxx/gnu/gcc-2.96/objdir/hppa1.1-hp-hpux10.20/threads/libiberty -Wl,-a,shared_archive -g -lstdc++ -liberty -lm -threads -o /xxx/gnu/gcc-2.96/objdir/hppa1.1-hp-hpux10.20/libio/testsuite/hounddog
<command line>: warning: The C standard requires whitespace after #define __STDC
_EXT__
collect2: ld terminated with signal 10 [Bus error]
/usr/ccs/bin/ld: Unsatisfied symbols:
   __check_eh_spec (data)
   __rtti_user (data)
   __rtti_si (data)
   type_info type_info function(data)
   __check_null_eh_spec (data)

   bad_alloc type_info function(data)
   exception type_info function(data)
   bad_typeid type_info function(data)
   __user_type_info type_info function(data)

It looks like these symbols should be code rather than data.

I wonder what is causing the whitespace warning.  The following warning
occurs a couple of times building libgcc.a:

_varargs
../../gcc/libgcc2.c: In function `__builtin_saveregs':
../../gcc/libgcc2.c:1297: warning: ICE: would have deleted prologue/epilogue ins
n

        (reg:SI 19 %r19)) -1 (nil)
    (nil))

and

_eh

../../gcc/libgcc2.c:2990: warning: ICE: would have deleted prologue/epilogue ins
