Instructions for the compilation of GCC under AIX 2.2.1:

1)  FTP the source to GCC 2.5.8 from prep.ai.mit.edu (or one of it's mirrors).
2)  Gunzip and untar the source somewhere.
3)  From outside the gcc-2.5.8/ directory that is created by the unarchiving
    of the tar, execute the command 'patch -p < gcc258diff'.  This will patch
    all of the necessary parts of the source.
4)  Change directory into gcc-2.5.8/.
5)  Execute the command:
	% configure romp-ibm-aix
6)  Execute the command:
	% make LANGUAGES="c"
7)  Execute the command:
	% make stage1
8)  In the Makefile, go to line 349, which looks like:
	XCFLAGS = -a -Nn3000 -Nd4000 -Np1200 -Nt2000
    Change it to look like:
	XCFLAGS =
9)  Execute the command:
	% make CC="stage1/xgcc -Bstage1/" LANGUAGES="c" CFLAGS=""
10) Execute the command:
	% make stage2
11) Execute the command:
	% make CC="stage2/xgcc -Bstage2/" CFLAGS=""
12) Execute the command:
	% make libobjc.a
13) To install, execute the commands:
	% make install
	% make install-libobjc
14) Enjoy.
