I was thinking about calling build_tools/make_version from configure.ac and
having it exported to autoconfig.h but it could get stale if you did a git
pull on the same branch and didn't re-run ./configure.  The issue I have
with the -DASTERISK_VERSION_NUM is that IDEs won't detect that and will
probably show the code as if it weren't defined.   I think the best way to
do this may be to have configure.ac run make_version but then have the
Makefile also run it and if it's different, just run sed on autoconfig.h to
replace the version.

You'd have to update:
configure.ac
autoconfig.h.in
makeopts.in
Makefile.in

Should be fairly easy though.
