OK, I was able to build and link libmesh with gcc 3.3.1. For that to
happen, the DLFLAGS have to be set to -Wl,-brtl. 

After this, there were problems compiling and linking the libraries in
the contrib directory. Most of them did fine after adding LDFLAGS = -lm

Now I am stuck with parmetis and gzstream. In both directories I get
linker errors. The compiler settings in Makefile.common are the following:

--------------
hosttype             = powerpc-ibm-aix5.1.0.0

CXX                  = g++
CC                   = gcc 
LDFLAGS              = -lm
DLFLAGS              = -Wl,-brtl
LIBS                 = 
FLIBS                =  -L/usr/local/bin/../lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3.1 -L/usr/local/bin/../lib/g
cc-lib -L/usr/local/pkg/gcc/gcc-3.3.1/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3.1 -L/usr/local/bin/../lib/gcc-lib

CXXSHAREDFLAG        = -shared
CSHAREDFLAG          = -shared
RPATHFLAG            = -Wl,-rpath,

For gzstream I get linker errors of the form 

--- Building Parmetis ------------------------
gmake[1]: Entering directory `/wrkdir/luthi/libmesh/contrib/parmetis/Lib'
Linking ../../lib/powerpc-ibm-aix5.1.0.0_opt/libparmetis.so

ld: 0711-317 ERROR: Undefined symbol: .MPI_Irecv
ld: 0711-317 ERROR: Undefined symbol: .MPI_Isend
--------------

and so on. For gzstream the error messages are

--------------
Linking ../lib/powerpc-ibm-aix5.1.0.0_opt/libgzstream.so
ld: 0711-317 ERROR: Undefined symbol: .gzopen

ld: 0711-317 ERROR: Undefined symbol: vtable for std::basic_streambuf<char, std::char_traits<char> >
--------------

and so on. The strange thing here is that std::basic_streambuf is not
found.

================

If I compile with xlC (with the following compiler settings)

CXX                  = mpCC_r -+ -q64
CC                   = mpcc_r -q64

there are some warnings about inlining

----------------
Compiling C++ (in optimized mode) src/base/dof_map.C...

----------------

and then there is a fatal error:

----------------
"/u1/uaf/luthi/wrkdir/libmesh/include/mesh/mesh_refinement.h", line 38.11: 1540-0836 (S) The #include file <ext/hash_map> is not found.
gmake: *** [src/geom/elem_refinement.powerpc-ibm-aix5.1.0.0.o] Error 1
----------------

Any hints are welcome.
