  Except the "configure" script doesn't create rlm_sql_mysql/all.mk.
You did.  You've got to add in the correct CFLAGS.  See the Makefile in
that directory for details.

  The old build system does figure that out.  The new one doesn't,
because not all of the modules have been converted over yet.

  This list really should be taken from the Makefile in that directory.

  If you're running it from the build directory, you need to set
LD_LIBRARY_PATH.  The need to set that is some of the reason why libtool
has such deep and bizarre magic.

  You should be able to just do "make install".  The new make system
automatically tracks dependencies all the way through to installed
files.  So change one C file, do "make install", and one file gets
re-built and re-installed.

  Very nice.

  There are some caveats, the "raddb" directory hasn't been updated to
use the new build system.  So you'll have to handle that manually.

  If it's too much of a pain, just use the old build system.  It's
extremely slow, but it works.
