Add the .Fx macro for specifying FreeBSD releases.
Add a bunch of missing standards to the .St macro.
Add Version 1 AT&T UNIX to .At macro
Updated the ".St -ansiC" macro to report "ISO 9899: 1990 (``ISO C'')"
You can also specify -iso9899, or -isoC. Use -ansiC-89 if you still need
the X3.159-1989 string reported.

(A pointer to a const was misused to avoid loading loading the same
value twice, but gcc does exactly the same optimization automatically.
It can see that the value hasn't changed.)
- avoiding strcmp("?" saved 12 bytes. gcc inlined the strcmp()
but this takes as much or more code as a function call. The
inlining was bogus because the strcmp() in the bootstrap isn't
standard.
- using a char instead of an int for the boolean `last_only' saved 8
bytes. Booleans should usually be represented as chars on the i386.
- simplifying the return tests saved 9 bytes.
- using putc instead of printf to print a newline saved 3 bytes of code
and 2 bytes of const data.
- avoiding `else's by always doing the else clause and fixing it up
saved 4+8 bytes.
gcc always generates large code for accesses to globals. For locals
it only generates large code if there are more than 128 bytes of
locals. It sorts scalar locals after array locals to pessimize for
space in the usual case when there are more (static) references to
scalars than to arrays.
Saved another 16 bytes (13 before padding) by adding a `continue'.
Fall-through tests normally save space, but here one of them made
gcc do space-unoptimal register allocation (it allocates ch in %bl
because preserving this register across function calls is "free",
but comparisions with %bl take one byte fewer than comparsions with
%bl).
- add ctm_conf.gnats from freefall
- add support for doing both the immediate mailout and the queued mailout.
- use "sendmail -odq -t" rather than "sendamil -t" to make it queue to
the mailqueue rather than immediately begin transmission. This allows
us to take advantage of our ordered dequeueing system without blowing
WC's T1 to hell with a 50 part mailout in parallel.
- bump the max ctm size from 3MB to 10MB.... This is mainly for the fast
list.
for entire SYS5 SHM segments. This is totally unnecessary, and so the
correct allocation of VM objects has been substituted. (The vm_mmap
was misused -- vm_object_allocate is more appropriate.)
we actually look for the *group* and not the user's gid. user daemon
has traditionally been group 31 (guest).
Also clear out the groups vector so that it doesn't inherit the groups
of the invoking user (ever run rwhod by hand before?) Unfortunately, we
can't empty the supplemental groups list because the !&@^#! egid is stored
in there! :-(
