F77 distribution.

I have on old gcc version 2.7.0
(/usr/local/lib/gcc-lib/rs6000-ibm-aix3.2.5/2.7.0/specs)

I have unpacked the 3 archives in the the same directory
/home/rs3/murea/src/gcc-2.95.2

$ mkdir /home/rs3/murea/src/build-gcc
$ cd /home/rs3/murea/src/build-gcc
$ ../gcc-2.95.2/configure --prefix=/home/rs3/murea/src/build-gcc
$ /usr/local/bin/make bootstrap     (the GNU make)
