Description john barry 2003-09-12 15:34:54 UTC 
Output of gcc -v:
Reading specs from
/usr/data2/local/gcc-3.3.1/lib/gcc-lib/mips-sgi-irix6.5/3.3.1/specs
Configured with: ../gcc-3.3.1.src/configure --prefix=/usr/data2/local/gcc-3.3.1
Thread model: single
gcc version 3.3.1

Compiler error generated while compiling with: gmake bootstrap:

While compiling : /libf2c/libI77/backspace.c

from file fio.h:2
from file stdio.h:18
from file internal/stdio_core.h:319

undefined type "__gnuc___gnuc_va_list"

Work around was to edit internal/stdio_core.h.
(1) #included  stdarg.h which defined : __gnuc_va_list
(2) changed line 319 from :
 	__SGI_LIBC_NAMESPACE_QUALIFIER __gnuc___gnuc_va_list _ap;
to:
	__SGI_LIBC_NAMESPACE_QUALIFIER __gnuc_va_list _ap;

then gmake bootstrap completed successfully.
Comment 1 Andrew Pinski 2003-10-06 20:55:27 UTC 
Fixed on the mainline by:
        * fixinc/inclhack.def (stdio_va_list): Removed _ap fix.
        (irix_stdio_va_list): Don't require leading printf, IRIX 6.5.21
        introduced some multi-line prototypes.
        * fixinc/fixincl.x: Regenerate.
Comment 2 Rainer Orth 2003-10-07 21:23:29 UTC 
Reopen to allow fixing for 3.3.2, too.
Comment 3 Rainer Orth 2003-10-07 21:26:34 UTC 
Could you please check that this patch

http://gcc.gnu.org/ml/gcc-patches/2003-10/msg00424.html

fixes the bug for you.  Please note that you need to regenerate
gcc/fixinc/fixincl.x for it to have effect.

I'm currently running a bootstrap of the current 3.3 branch with this fix
include.  It may be possible to get the fix into 3.3.2 if it can be confirmed
to work and is sufficiently low-risk.
Comment 4 Rainer Orth 2003-10-09 18:05:26 UTC 
Fixed for 3.3.2, too:

I have the opposite experience.

With our irix 6.5 system, gcc 3.3.1 built fine, but 3.3.2 fails to build on this
file.
