I've been running elm 2.3 PL6 for several months, and just installed PL11 last
week, on a DECstation 5000 and two DS2100's running Ultrix 4.1.

The only problem I had with the installation was trying to compile the
thing with Gnu C, rather than the standard C compiler:  the problem seems to be
with inconsistencies in the Ultrix header files (e.g. typedef int time_t; was
in some headers, rather than using long int).  When I gave up on Gnu C's nice
strict type-checking and used the much more lax MIPS C compiler, everything
worked fine.  (Retorical FAQ:  When will DEC get Unix right?)

I did run into a slight problem with the VAX Ultrix 4.1 compilation of the
src/signals.c file, due to the bizarre handling of the "void" type in its
C compiler, but the following patch took care of that:
