[postgis-devel] Autoprobing java source files

[Markus Schaber]

Hi, Strk,

After some erroneous tries and reading the appropriate sections of the
"Make Manual", I now managed to do Make something acceptable, and
checked it in.

I learned that make will try to re-build missing included files if
appropriate rules exist, and then automatically re-run the whole machinery.

So now the behaviour is the following:

- If sources.inc is not present at a make run, it is automatically
rebuilt (if "find" works), and a warning / notice appears on the screen.

- make clean leaves sources.inc as it is.

- make distclean removes sources.inc after calling clean.

The funny part comes if you run "make distclean" without having a
sources.inc, then it is recreated just to be deleted again.
