Link issues with gcc 4.4.0 on AIX 5.3

["Eric Fernandez" <efernandez at physiomics-plc dot com>]

Hi,

I have compiled gcc-4.4.0 on AIX 5.3 (using my current gcc-4.3.3 and GNU
toolchain) with no problem (I also compiled PPL and CLoog). I use the
AIX linker and used --disabled shared. However, when trying to compile a
simple c++ program, I get this error:
collect2: library libstdc++ -lsupc++ not found

That's very strange, because 4.3.3 had no problem finding these
libraries. My GNU toolchain and libs are in a local directory and are
very parallel:

$PREFIXGNU/lib/gcc/powerpc-ibm-aix5.3.0.0/4.3.3 contains:
finclude/       include-fixed/  libgcc.a        libgomp.a
libgomp.spec    libstdc++.la*   libsupc++.la*   pthread/        include/
install-tools/  libgcov.a       libgomp.la*     libstdc++.a
libsupc++.a     ppc64/

and $PREFIXGNU/lib/gcc/powerpc-ibm-aix5.3.0.0/4.4.0 contains the same
file names.

gcc-4.4.0 was configured with:

bash-2.05a$ gcc -v
Using built-in specs.

gcc-4.3.0 was configured with:

bash-2.05a$ gcc -v
Using built-in specs.
Target: powerpc-ibm-aix5.3.0.0
Configured with: /hpc/work/fernandz/gnusrc/gcc-4.3.3/configure
--enable-threads --enable-languages=c,c++ --prefix=$PREFIXGNU
--enable-threads --disable-shared --enable-version-specific-runtime-libs
--disable-nls --with-gmp=$PREFIXGNU --with-mpfr=$PREFIXGNU
Thread model: aix
gcc version 4.3.3 (GCC) 

LIBPATH is set to:
LIBPATH=$PREFIXGNU/lib/gcc/powerpc-ibm-aix5.3.0.0/$GCC_VERSION:$PREFIX/l
ib:$PREFIXGNU/lib:/usr/lib:/lib

where $GCC_VERSION = 4.3.3 or 4.4.0 depending.

I don't understand the problem with 4.4.0.

Thanks for your help,
Eric
