Well, I've been anxious to get Sendmail 5.64+ installed on my PC RT, and,
unsurprisingly, I've run into a bunch of problems.

First and foremost, the RT does NOT have an 'flock' function call.  It does
have a 'lockf' function call, which locks certain 'regions' of a file.  Per
a previous request for info on 'lockf', Ed Clarke (clarke@acheron.uucp),
posted a sample change he made in "alias.c" to use 'lockf' instead of 'flock'.
I made similar changes to the rest of the 'flock' calls, and those APPEAR to
have worked.  The reason I say "appear" is because the man page for 'lockf'
says it does not work with standard, buffered I/O, which is what Sendmail
uses. :-)  So I'm not sure if this is actually the correct way to handle the
situation.  I'm wondering if a call to 'fcntl' might not be more appropriate.
I don't have a man page for it, though, so I'm looking for info on it. (Hint,
hint...)

OK.  Below are the rest of the changes (as far as I can remember) that I made
to the distribution version of Sendmail 5.64 with the IDA/BIU enhancements,
which I got from uxc.cso.uiuc.edu:

. Set the compiler flag '-DBSD_INCLUDES', so <sys/dir.h> would include 
  <dirent.h>, which has the necessary definition of 'DIR' used in "queue.c"
. Added "getenv.c" and "setenv.c" to the /src directory, copied from the
  /support directory of the distribution, edited Makefile accordingly
. Changed the 'getla()' routine in "conf.c" to also return 0, since I don't
  think the RT has anyway of determining the load average (I don't use this
  feature anyway); removed 'getloadavg.c/.o' from the Makefile
. Changed all the calls to 'flock' to 'lockf' in "alias.c", "daemon.c", and
  "queue.c" as demonstrated by Ed Clarke in his post to comp.sys.ibm.pc.rt
. Set the compiler flag '-DVMUNIX', which works on the RT except for one
  #ifdef in "deliver.c", which tries to assign FORK to 'vfork'.
. Changed "sendmail.h" to #include <fcntl.h>, since two or three other files
  needed definitions from this include file.
. Added EPROCLIM = 98 to the list of returned error flags (thanks again to
  Ed Clarke for that info)
. It is currently compiled with only DBM defined, not NDBM or SDBM; all the
  other default options were left the same (I think), including having
  NAMED_BIND on, etc.  (named is running :-)

Now all this compiles fine with only a few warnings here and there.  But for
some reason, Sendmail doesn't appear to function properly.  For one thing,
if you try to run sendmail/newaliases/mailq with the '-d' flag, the only debug
output you get is "Sendmail 5.64+", then a nice "Bus error (core dumped)" 
message.  HOWEVER, if you also run with the '-C' flag (to NOT use the frozen
configuration file or something), the debug option works as expected.

Even worse, though, is that mail sent to the new sendmail daemon from a remote
host fails with a "couldn't execute /usr/lib/sendmail" error, although local
mail works fine.

Finally...
On the topic of the last item, I also (successfully?) compiled gdbm 1.3, which
is the GNU version of DBM/NDBM.  I installed the gdbm.a library in /usr/lib,
and tried to link Sendmail 5.64 with it, but I get errors from syslog telling
me that the database /etc/sendmail/aliases could not be opened when I tried to
run newaliases and sendmail.  Has anyone compiled/used GNU's dbm?  Does it
work correctly in Sendmail?  (I also installed the 'ndmb.h' include file from 
the GNU dbm in /usr/include.)

Any help/suggestions with any of this would be GREATLY appreciated.
