Hello. This was my question:

The documentation for Mysql says that ld is "broken" for this version of
DU (4.0D, no patches) and suggests using an *older* 4.0c version of ld.

This proved to be the case. I used this command to run configure and
successfully compile the distribution:
env CC="cc -pthread" CFLAGS=-I./include CXX=gcc CXXFLAGS=-O3 ./configure \
--with-low-memory --with-named-thread-libs="-lpthread -lmach -lexc"
I removed "-lc" from the with-named-thread-libs variable list recommended
in the docs, thanks to Simon's suggestion. If -lc is included in that
list, I get the above unresolved _exit symbol. _exit is in the libc
library, so removing it from the list must have left it free to get the
default libc from the system. I plan to write the MySQL developers to
tell them how this helped. The default for named-thread-libs does include
the -lc, so leaving out the named-thread-libs variable altogether didn't
help.
This was built with CC=cc and CXX=gcc per another suggestion in the
documents. I am hoping this doesn't cause a problem down the line.
Here's more detail:
If I use gcc for both CC and CXX, I run into a complaint about the format
of a c_asm.h file. The docs say to just put a blank c_asm.h file in
(dist)/include for that problem, but then there's an unresolved symbol for
asm. I could see that it was indeed being used in (dist)/strings/bfill.c.
I have plenty of memory, but a compile without --with-low-memory ran out
of memory on a yacc routine, if I recall correctly. I guess it hit a
loop somehow. The docs suggested the --with-low-memory workaround.
In the distribution INSTALL-SOURCE file, and identically in the included
mysql manual, there are some osf tips that deal with these issues, in two
sections, one for Alpha-DEC-Unix and one for Alpha-DEC-OSF1. Also the
general comments a the top of the "Problems Compiling?" section were
helpful.
There were a few compile warnings about char type conflicts, similar to
warnings I have seen on other compiled packages. I am hoping this will
not cause a problem with running the package.
Here is the statement where things were blowing up, when I had -lc
included in the configure named-thread-libs variable:
-----------------------------

collect2: ld returned 1 exit status
/usr/bin/ld:
Unresolved:
_exit
*** Exit 1
Stop.
*** Exit 1
Stop.
Best wishes to anyone in the future compiling this program. The previous
version 3.21.33 that I installed some time ago from binary runs great and
is very fast, except that it very occasionally loses a thread when under
moderate load. That binary no longer seems to be available on the MySQL
site, however, so I wonder if under heavy loads there might be more
problems with it. Our load is usually quite light. This 3.22.27 version
just compiled has some nice features added, and I hope it will be even
more stable than the 3.21 version has been for us.
