[Ctool-develop] build system refinements

[Stefan S. <se...@sy...>]

hi there,

I committed some new files for a new build system.
Right now that consists of a set of files needed
for autoconf / configure, as well as a single
Makefile template ('Makefile.in'), which may
eventually replace src/Makefile.

To try it out, step into the root directory and
call 'autoconf' to generate the 'configure' script.
Then run './configure' to generate the new src/Makefile.
Finally, compile by running 'make -C src'.

I'd like to work on this further to be able to do a
full build (the library, some tools, tests, etc.)
with a single command ('make test', say), and that
on build directories that are *outside* the src directory.
That would especially be practical if you want to make changes
and test them immediately on different platforms / configurations.

Anyways, before pushing that idea further I need to refine the
configure tests to be fully portable, i.e. allow to detect
different versions of bison/yacc, preprocessor options, etc.

Best regards,
		Stefan
