No, sorry. But if you are interested I am willing to help. I don't
think "faking it" is a good idea. Instead, we should probably change
the code something like this:
/* e.g. OPENAXIOM="C:/Program
Files/OpenAxiom/lib/open-axiom/i686-pc-mingw32/1.1.0 */
if (pAXIOM=getenv("OPENAXIOM")) {
strcpy(AXIOM_exe,pAXIOM);
strcat(AXIOM_exe,"/../../../../bin/open-axiom.exe");
strcpy(AXIOM_cmd,pAXIOM); strcat(AXIOM_cmd,
"/../../../../bin/open-axiom.exe");
strcat(AXIOM_cmd," --system=\""; strcat(AXIOM_cmd,pAXIOM);
strcat(AXIOM_cmd,"\"");
strcpy(ENV_AXIOM,"OPENAXIOM="); strcat(ENV_AXIOM, pAXIOM);
} else { /* We need the AXIOM variable! */
printf("You must set the OPENAXIOM environment variable, e.g.\n");
printf(" OPENAXIOM=C:/Program
Files/OpenAxiom/lib/open-axiom/i686-pc-mingw32/1.1.0\n");
exit(1);
};
Then the user would have to set the OPENAXIOM environment variable
appropriately for their installation. The /../../../.. prefix allows
the open-axiom.exe to be located relative to this path and the path
itself is passed via the --system option.
Warning: I haven't tested this, but I may get a chance to try it later tonight.
One question is: Do you want to be able to run both the original Axiom
and OpenAxiom in the same TeXmacs session? Or is configuring it for
just one or the other sufficient? If you want both (or maybe all
three? :-) then we need to do a little more work.

Bill Page.
