environment:
IBM AIX 6.1 TL0 SP2
XC C/C++ 9.0

------- Comment #2 from tammer at tammer dot net  2008-01-15 11:28 -------
Hello,
currently I am working with Ralf Wildenhues (libtool, autconf, automake,
config) to get AIX 6.1 in. The libtool (branch-1.5 / HEAD) and config.guess now
recognizes AIX 6.1 as -> powerpc-ibm-aix6.1.0.0.

I have not yet regenerated the complete build environment of gcc 4.2.2 with the
above tools. As gcc is a very large project I am not comfortable in rebuilding
the whole shebang...

  Rainer

------- Comment #4 from dje at gcc dot gnu dot org  2008-01-22 22:15 -------
libsdc++ does not appear to be configured correctly on AIX 6.1. 
libstdc++-3/libmath/stubs.c and /usr/include/math.h are not interacting
correctly and functions, such as fabsl, are getting redefined by math.h,
causing problems.

Hallo,
this is exactly what I feared. But unfortunately I do not know exactly how to
fix this. I have attached the math.h from AIX 6.1. Maybe you can have a look at
the header and find a quick fix ?

[Bug libstdc++/34794] build of gcc 4.2.2 fails on AIX 6.1 / libstdc++-v3/libmath/stubs.c:47

[dje at gcc dot gnu dot org]

------- Comment #7 from dje at gcc dot gnu dot org  2008-01-24 17:23 -------
I have upgraded libtool and all of the configure scripts in mainline.

The problem with stubs is because the libstdc++-v3 configure machinery is not
recognizing that AIX libm already provides all of those functions, as it
detects with AIX 5.  I am continuing to investigate.

AIX 6 math.h "optimizations" completely confuse GCC configure looking for ISO
C99 and long double support.  It looks like this will require fix-includes
magic.

Replacing gcc's "include-fixed" version of math.h with the include-fixed
version from AIX 5.3 gets farther.  AIX 6 math.h is going to need to be tweaked
and we need to figure out what parts of the file need to be commented out.  I
suspect all of the "inlined" functions.

Hello,
I can try with the updated source and the AIX 5.3 math.h ...

What is the correct SNV tag for the "updated" version or did you only update
you local copy ??

Bye

The AIX 5.3 fixed math.h does not make the build completely succeed, it just
gets farther.

GCC currrent mainline has the other changes.

Is this the problem you mentioned ?? 
The 4.2.2. release did not crash on this place.

------- Comment #15 from dje at gcc dot gnu dot org  2008-01-29 14:40 -------
First, mainline bootstraps fully for me on AIX 6.1.  I am closing this bug
about AIX building libstdc++ as resolved in GCC 4.3.

Second, "... and you are right" is completely meaningless without context.  I
have no idea what you are referring to.  Make sure that the process limits are
large enough.  Building on AIX 6.1, I did experience random system call
failures during the build, but simply restarted and the build completed.

If you can provide a more detailed and repeatable failure, please open a new
GCC bug.

By the way, I am using a recent GCC compiled for AIX 5.3 with the "fixed"
headers removed as the bootstrap compiler on AIX 6.1.

------- Comment #17 from tammer at tammer dot net  2008-01-29 15:17 -------
I have used IBM XL C/C++ 9.0 to bootstrap the gcc 4.3 compiler. I will test the
build with the gcc 4.2.2 build from www.perzl.org (Mr. Perzl from IBM Germany)
for the initial stage1.

Thanks for your help.

IBM XLC has had problems bootstrapping GCC.  I am surprised you got to
libstdc++ for GCC 4.2.2.  If you were using XLC, then that likely is the
problem and it miscompiled the stage1 GCC compiler.
