Amar Takhar b1c441ff73 Commit the new build system (complete re-write), this includes several changes:
* Sane C/CXX/CPP/LDFLAGS
 * --with/--without settings
 * Proper gettext support
 * System portability changes (to support OS X and all other unix-like osen)
 * Features to allow for proper compile time settings (support exists features
   need to be added)

This comes with no warrenty at the moment, auto3 and asa support are both
incomplete/non-existent, there is no documentation and some conftests still nee$
to be written.

It's still incomplete try it at your own risk!

Originally committed to SVN as r1865.
