Trying to build oleo-1.2 on an IBM RS/6000 (AIX 3.2.3), I encountered
several difficulties:

I ran ./configure, then changed prefix to /usr/gnu, and CFLAGS to -O.
gcc 2.2.1 is on the system.

1. gcc got fatal signal 6 when compiling regions.c, so I recompiled it
without optimization and got no complaints. [I'm not going to report
this gcc bug to bug-gcc since the current gcc is 2.3.3]

2. utils.c gets compile errors (namlen) with gcc and system's cc, but
not system 'bsdcc', so I used that.

3. io-utils.c has a function 'div' which conflicts with one in the
system, defined in stdlib.h (!). I changed 'div' to 'loc_div' without
incident.

4. io-x11.c redefines getenv in a different way than stdlib.h (no 'const'),
so I ifdef'ed it out.

5. You don't need -ltermlib on AIX.

6. ualarm.o apparently needs to be included in the 'objs' line in
Makefile, since 'alarm_interval' can't be resolved.

7. gcc complains a couple times about assignments between incompatible
types, but they are warnings, and on rs/6000, they shouldn't matter.

8. The executable doesn't work! On the console, with DISPLAY defined,
when I start oleo, I get the startup message in my xterm, then
nothing. No windows, nuttin. Then only thing I can do is send
2 ^C or ^Z. Perhaps this is just ignorance on my part.

9. The INSTALL file refers to a mailing address in README, but
README doesn't show a mailing address.
