Please help me gcc install


Hello, i`m trying to install gcc(gcc-2.95.2) on to a IBM powerpc aix 4.2.1.0.

source download ftp from 128.97.2.211
and i try this
o   mkdir ../gcc-2.95.2.obj
o   cd ../gcc-2.95.2.obj
o   ../gcc-2.95.2/configure --host=rs6000-ibm-aix4.2.1.0 --with-cpu=common
o   make bootstrap-lean


however, i`m getting the following errors after configuring the compiler for
installation:


        touch s-genrtl
        cc -c  -DIN_GCC -DHAIFA    -O2 -g   -DHAVE_CONFIG_H    -I. -I../../gcc-c
