Subject [PATCH] Make Configure generate ap_config.h
Date Thu, 05 Mar 1998 03:43:15 GMT
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.
