Problem building G++ from CVS under AIX 4.2.1

Hello

today I had a problem building the g++ part of gcc from the CVS
repository. It broke whith the following error:

I have configured gcc whith the following options:

----------8<----------------------------------------------------
../configure --enable-languages="c,c++" --enable-shared
--prefix=/work/gcc_test
----------8<----------------------------------------------------

If it is neccessary to provide more information, I could send the whole
buil log (1.5 M uncompressed) to everybody interested.
