            Bug ID: 63714
           Summary: AIX (5.3.7, xlC v11) fails to bootstrap for gcc 4.9.2,
                    4.8.3 and 4.7.4
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: aixtools at gmail dot com

The announcement of gcc 4.9.2 got me started - time to get gcc packaged. As
much as possible I want to be packaging with tools I have assembled/packaged
myself. And, although I failed miserably years ago - now is the time to move
forward.

In the details below (and I apologize if my emphasis is wrong - I have a lot to
learn about how gcc is organized) you can see that the failure for GCC 4.9.2
and GCC 4.8.3 are at the same spot. GCC 4.7.4 looks as if it wants to complete,
but is getting lost - after coming a long way "configure" complains:

checking for powerpc-ibm-aix5.3.0.0-gcc...
/data/prj/gnu/gcc/objdir/gcc-4.7.4/./gcc/xgcc
-B/data/prj/gnu/gcc/objdir/gcc-4.7.4/./gcc/ -B/opt/powerpc-ibm-aix5.3.0.0/bin/
-B/opt/powerpc-ibm-aix5.3.0.0/lib/ -isystem /opt/powerpc-ibm-aix5.3.0.0/include
-isystem /opt/powerpc-ibm-aix5.3.0.0/sys-include   
checking for suffix of object files... configure: error: in
`/data/prj/gnu/gcc/objdir/gcc-4.7.4/powerpc-ibm-aix5.3.0.0/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make[2]: *** [configure-stage1-target-libgcc] Error 1

So, as it is getting much closer this is what I want to work on and should be
considered the "bug" of this report.

Additional Info (and request)

GCC 4.9.2 and GCC 4.8.3 exit at a different point in time compared to GCC
4.7.4. (This can be a new bug later):

Configure command:

CPPFLAGS="-I/opt/include" CFLAGS="-I/opt/aixtools/include -qlanglvl=extc89"
./configure \
        --prefix=/opt \
        --sysconfdir=/var/gcc/etc \
        --sharedstatedir=/var/gcc/com \
        --localstatedir=/var/gcc \
        --mandir=/usr/share/man \
        --infodir=/opt/share/info/gcc --with-gmp=/opt --with-mpfr=/opt
--with-mpc=/opt --enable-languages=c,c++

Small bits:
when I do not include -qlanglvl=extc89 as part of CFLAGS I get the following
result:
root@x064:[/data/prj/gnu/gcc/objdir/gcc-4.7.4]make
[ -f stage_final ] || echo stage3 > stage_final
/bin/sh[3]: 0403-057 Syntax error at line 1 : `-qlanglvl=extc89' is not
expected.

Besides AIX 5.3 TL7 CSP install, plus xlC/vacv11 FP19 The following is
installed:

Note that ./configure reports mpc 0.80+ (while 1.0.1 is the lowest level
currently available for download); mpfr 2.4.0+ (while 2.4.2 is needed). As O
already had gmp 5.0.5 packaged I did not test lowest levels there.
The web-based documentation does say mpfr 2.4.2 is needed (required by mpc
1.0.2).

Looking forward to a productive collaboration.

p.s. If you want to read my notes collected while I was working (waiting for an
gcc account) you may read http://www.aixtools.net/index.php/gcc

p.p.s. If I have omitted something "basic" to make a good bug-report - please
be kind and patient. I will give this as much time as possible, and warn you
when that time is severely limited.
