So is VC.  The essential thing on every build of apache is to start it
with the -X flag in httpd 1.3 - you will get ONE worker process and no
parent process.  You can now step it, debug it or whatnot.

If you omit -X (or in 2.x, the -DONE_PROCESS flag) you will find yourself
debugging the PARENT process.  In that case, you have to attach to the
pid of the worker process you want to debug.
