           Summary: How to config gcc under AIX 4.2.1
           Product: gcc
           Version: 3.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: lq2001ca at yahoo dot ca
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: gcc 3.1.1
  GCC host triplet: AIX 4.2.1
GCC target triplet: c/c++

I built gcc 3.1.1 compiler under aix 4.3 successfully when I used following 
configuration:
../gcc-3.1.1/configure --prefix=/p/benjamin/usr/gcc-311-mlib-aixthread \
        --enable-languages=c,c++ \                                      
        --enable-threads=aix \                                          
        --disable-shared
My c++ multithreading program works properly. But My c++ multithreading program 
works properly, It gets core dump And I built gcc 3.1.1 under aix 4.2.1 
successfully wiht same configuration with aix 4.3. And I build my c++ 
multithreading program using -O2 -pthread -fexceptions -fstack-check 
compilation optione and -pthread link option. So I want to know correct 
configuration for gcc 3.1.1 compiler which support mulithtreading or 
compilation/link option under aix 4.2.1.  And I also found aix 4.2.1 missing 
pthread directory under lib(gcc 3.1.1) directory, aix 4.3 has this directory. 
So I wonder aix 4.2.1 need this directory or not or Maybe I'm missing some 
setting to build gcc 3.1.1 compiler. Any suggestion or help will be appreciated.

Thanks in advance.
