Savant is the name of the project that I wrote the macro for. Note I'm not
any kind of autoconf expert, this is just the macro I wrote way back for
this. I'll attach my acinclude.m4 which contains the full macro and not
too much else.

I don't know what you mean by this, but if I knew I could probably help
make it happen upstream. Could you elaborate for me?

Well, there are a few files and they have to be compiled. In my mind that
justifies a library. Otherwise everyone handles this problem slightly
differently - either copying the code in and getting out of sync from time
to time, or something else.

Yes, the current Makefile seems to work fairly well - it's just the lack of
a standard place for the headers and the "precompilable" stuff that is the
minor annoyance I see. A "make install" could address both of those
issues.

I've discussed this with him and I think he's willing to tackle it. It's
been some time since I've discussed it with him though.
Later,

AC_MSG_WARN(
The regular \"makedepend\" that ships with Xwindows
has hard limits on the number of files that it can handle and
SAVANT has more files than it can deal with. The developers of
SAVANT provide two easy solutions to this problem. One is to use
g++ to generate dependencies (even if you're compiling with some
other compiler) and the other is to ship a binaries of X makedepend
with its static limits increased. However configure could not
locate any version of the program \"g++\" in your path nor can it
find a binary version of \"makedepend\" installed by SAVANT for your
OS. Since configure cannot find either one you'll need to build the
dependencies some other way - perhaps using a compiler flag of the
c++ compiler you're using or making a soft link to a compatible
binary installed by SAVANT. Please see the notes in the README
regarding makedepend. If g++ _is_ installed on your system please make
sure the directory it is in appears in your path - your path right now
is:
$PATH )
