[PATCH] Make Configure generate ap_config.h

[Rasmus Lerdorf <ra...@lerdorf.on.ca>]

I think the following patch to Configure will make it generate an
ap_config.h file suitable for inclusion by external modules.  It would be
nice to also have a switch on Configure which makes it do nothing except
generate this file, but that seems to require more than this simple
change.
