Well, since I have it up for a while - here are the config files. I don't
remember whwther I needed to edit any *.c files - so feel free to test it. (:-)
But beware - some of the bugs are copyrighted by me (:-). Anyway, it was tested
on AIX/370 1.2 and AIX/370 1.2.1 (the files "config.h", "s-aix370.h" and
"m-ibm3090.h" are for AIX/370 1.2.1 - the difference between 1.2 and 1.2.1
shouldn't affect you, I think).
