mm 0.91 has been built on an HP-9000/735 running HP-UX 9.0 using c89
(make hpux).  There are now NO warning messages whatever from the
compiler, since appropriate source code changes have been made to
completely eliminate them.

I have not bothered this time to build mm-trans, which needs the
missing re_comp() and re_exec() functions, since it is used only to
convert TOPS-20 mail files with CR LF line terminators to UNIX LF
terminators.  Our TOPS-20 system was retired on Halloween, 1990.

mm 0.90 has been built on an HP-9000/735 running HP-UX 9.0 using cc
(NOT c89).  You can safely ignore the messages

cc -g -DDEBUG  -I../ccmd  -DUSAGE  -c misc.c
misc.c: 318: warning- RS redefined

cc -g -DDEBUG  -I../ccmd  -DUSAGE  -c seq.c
seq.c: 28: warning- RS redefined

The symbol RS is defined in <sys/syscall.h>, but overridden here with
a private definition.

In s-hpux.h, I added a

#undef setpgrp				/* HP-UX 8.0 or later */

since setpgrp() on HP-UX 8.0 and 9.0 at least (the only two I could
check) takes no arguments.

The re_exec() and re_comp() routines used in mm_trans.c are not
supplied by HP.  Rather than rewrite the code to use the compile() and
step() equivalents, I chose to build the Free Software Foundation GNU
regex package (version 0.12), storing it in a subdirectory named
regex-0.12, and modifying the Makefile to load it.
