XSubject: shortnames.h mods
XX-Mailer: Elm [version 1.5]
X
XDave,
X
XHello. I have just finished installing Elm on my 68k unix box running
XUnisoft Uniplus+ sysvr1. Unfortunately the C compiler doesn't support
Xlong variable names so I had the dubious honor of updating shortnames.h
Xto include several new variable and function names. I also do not have
Xthe setvbuf() function. I modified filter.h to delete it. I am enclosing
Xmy changes if you are interested...

XHere's the shortnames.h stuff I told you about. Hope its helpful -
Xbut you probably don't need it, being that you use a real
Xcompiler...
X
XAlso - has reply.c been posted to mod.sources? I'm looking
Xforward to receiving it. That's the last link I need before
XElm gets up and running.
