* A little utility function to generate header info.

* Yes, it would be possible to do this using more "native" autoconf
|
||
|
|
* features, but I personally find this approach to be cleaner.

* The output of this program is generally written to art_config.h,
|
||
|
|
* which is installed in libart's include dir.
