Debugging httpd

[Tim Bray]

Hi... I'm back to work on mod_atom and chasing a weird bug around.   
Anyhow I totally can't figure out what some apr code is doing so I  
wanted to step into it with the debugger.  This sounds lame, but I  
can't figure out how to build an httpd that has APR linked with debug  
information.

What are the approved incantations to make an httpd with some control  
over the -O and -g options?
