 I am posting to ask what is known about using X V11R4 clients when one does
not have time (or the experience!) to build an X V11R4 server.  Before 
everybody reaches for the key which they have bound to "RTFM", let me say
that I am Reading The Fine Manuals which were on the R4 tape, but there is a 
lot go get through, even for an Evelyn Wood Speed Reading graduate.

 (Aside: I downloaded X V11R4 from osu-cis!  Thanks Karl, et alii!!).

I compiled X V11R4 on a U6000/70 (Sequent S/27) using gcc 1.37 -- clients only.
The clients mostly run -- some of them ask for ISO fonts, but they work when
I use the -font  option to use a font actually installed on R3.  Some clients
use "courier" (Adobe, no?) fonts.

 Is there a quick way to examine C code of an X R4 program to see if it is
not compatible with R3?  If I run the program and it bombs, that just might
mean that I screwed up the port, not that the client is incompatible.

 (This port is not a Unisys product: I cannot supply copies to anywhere but
sites owned by Unisys Corporation).
