Here is how I managed to get X11 R3 running on an RT without too much trouble.
We are still running a very old version of 4.3 here, but I think this trick
still may help those who are using later versions.
The program below runs hc first, then if that fails, runs pcc with the
same arguments. You might have to change "/bin/hc" to "/bin/hc1.4"
to get this to work for you.
Compile this, and call it xcc. Now install xcc in /bin or wherever,
and change the RT.macros file to use xcc rather than cc as the c compiler.
You might also have to change the c compiler flags in
server/ddx/ibm/apa16/Imakefile to use -g instead of -O.
After doing the above I can now recompile the entire X distribution without
any problems. I get lots of fatal error messages from hc, but pcc compiles
the same files without complaint. You may still find one or two problems,
particularly if you haven't applied some of the official patches, but in
general this hack makes things managable.
