[fa.laser-lovers] ditroff special chars

We've been having this problem....

We have some hard core math freaks here at the UofMn who want to put many many
math symbols from the various Imagen fonts into the Imagen char set for DiTroff.
On the surface, this appears simple enough.  You just go into makedev.c and
change the "NCH" constant to a nice large number.  Then you edit the DESC file
to add a couple hundred new names to the charset, and run makedev.  This works
fine.  There do not appear to be any constants to change in DiTroff.

Unfortunately, when you run ditroff, it ignores all instances of special chars
whose ordinals are greater than or equal to 221.  255 I could understand but
221?  At any rate, I will not have time to do any serious code tracing for
several months but would like to see this work.  Has anyone run into this
problem before?  People are presently overloading character names, and/or
editing the DESC file to suit the paper which they are working on this week.
This is a real pain.
