autogen.sh produces (and runs) the "configure" script.  You don't have to
re-run autogen.sh unless you change its sources, things like configure.in
and Makefile.am.  Otherwise, you can just re-run "configure".  (It's
quicker.)

If you do:

        ./configure --with-tdsver=7.0 --enable-threadsafe=no

you should get a config.log that says:

$ grep -C threadsafe config.log
generated by GNU Autoconf 2.57.  Invocation command line was

  $ ../configure --with-tdsver=7.0  --enable-threadsafe=no

--
configure:10054: result: no
configure:10296: checking threadsafety
configure:10304: result: disabled
                         ^^^^^^^^ that verifies it.  

The "configure" script will *not* complain if you hand it an invalid
switch.  That's actually a feature, believe it or not.  So it's good to
check the log.

Sorry.  I was trying a shortcut.  Here's the long version.  Bear in mind,
I don't have a Mac.  I'm just talking about how the build works.  

By the time you see:

you're almost home, yaar.  You've built the FreeTDS libraries.  All that's
left is to install them, move them to /usr/local/lib or wherever.  Before
it installs the libraries for you,  "make" builds tsql and freebcp, both
of which are nice to have.  It's stopping there, because of the threadsafe
problem.  

The right way to fix that (I think) is to reconfigure, as above, then
"make clean; make; make install".  That should allow tsql and freebcp to
be built normally, albeit without thread support.  

A cheap workaround (my earlier suggestion) is to trick make into thinking
it worked.  Make compares the ages of its inputs and outputs to decide
what to compile, so if you "touch tsql", it thinks tsql was built and goes
on to the next thing.  The next thing is freebcp, which is where you
stopped.  You could touch that too, and probably everything would be fine
... except you wouldn't have tsql and freebcp, of course, just empty files
by those names.  

HTH.  :-)  Now, I'm sure where you are, the sun is shining, and as a
matter of fact, it will be here, too, before too long.  But before then, I
think I'll get some sleep.
