I just tried installing MH 6.6, and ran into a problem that I had also
noticed with version 6.5. uip/Makefile has the lines:
all: version.o $(CMDS) $(MISC)
@version.sh; $(CC) -O -c version.c
This causes the following to happen:
1. version.c is compiled into version.o.
2. All the utilities are compiled and linked.
3. version.sh is run to generate a new version.c, which is
then compiled.
As a consequence, the hostname in version.o is incorrect the first
time the utilities are made. After that, everything is OK.

P.S. I first tried reporting this to bug-mh@ics.uci.edu, but got back
a message from the mailer saying:

I reported this say "problem" about a year ago. I was told that it was SUPPOSED to work that way. The intention is that if you haven't made any changes or recompiled anything, then your version number and hostname should be the same as everyone else's. In other words, the version string is intended to show the last place that made changes to the system. Something like that anyway.

Inside of quotes, it is not necessary to escape newlines for programs like awk and sed. An escaped newline becomes a space. The result is that awk sees a program that is all on one line, and the new awk doesn't accept this (the behavior, though incompatible, has been shown to be correct according to the awk definition, and we have to be able to handle this). After fixing the awk script, it's a pain to get version.c rebuilt by the makefile, and the existing version.c doesn't compile.
