System: AIX vlad 3 4 0005BA2F4C00

>Description:

gcc -mcpu=630 -maix64 does not pass the path to the pcc64 multilib to
collect2.  Note that I applied
http://gcc.gnu.org/ml/gcc-patches/2001-02/msg00496.html , that is on
the mainline but not on the 3.0 branch (even though it probably should
be).

>How-To-Repeat:

Compile any 64-bit C/C++ that refers to libstdc++ or libgcc using
-mcpu=630 -maix64.

>Fix:

Do not use -mcpu=630 with -maix64 during the link.

 No, it is not fixed in 3.0.3, and the patch you point do do not seem
 to relate to this problem.  This is not a configure/build
 etc. problem, it is a problem in gcc, the problem is that the -mcpu
 switch overrides the -maix64 switch.  So please change it back to
 analyzed, as I have no right to do that.

    which should be in gcc 3.0.3 and the gcc 3.1 CVS mainline.
