[Bug c/35460] New: undefined reference to `__builtin_stdarg_start' when compiling 2/29 snapshot on OpenBSD

[michael dot a dot richmond at nasa dot gov]

When I attempt to compile the snapshot of 2/29/08 on OpenBSD 4.2 I get the
following message:

libcpp.a(errors.o)(.text+0x258): In function `cpp_error':
/home/mrichmon/gcc-4.4-20080229/libcpp/errors.c:141: undefined reference to
`__builtin_stdarg_start'
libcpp.a(errors.o)(.text+0x3a0): In function `cpp_error_with_line':
/home/mrichmon/gcc-4.4-20080229/libcpp/errors.c:174: undefined reference to
`__builtin_stdarg_start'

Support for __builtin_stdarg has been removed.  I guess this is still
referenced
in OpenBSD headers?

------- Comment #2 from pinskia at gcc dot gnu dot org  2008-03-05 03:18 -------
This is a bug in the openbsd headers.  We most likely should fixincludes them
to use __builtin_va_start instead.

See PR 26264 and http://gcc.gnu.org/ml/gcc-patches/2002-07/msg00737.html for
more information on why this was removed.

------- Comment #5 from andreast at gcc dot gnu dot org  2008-12-31 20:03 -------
This particular issue is fixed. The bootstrap itself will fail (at least here
on x86_64-unknown-openbsd4.4).
Next patches coming.
