Hi Bob,

thanks for the quick reply.

Done. But shouldn't it be called --enable instead of --with? I thought 
--with was for external packages, and --enable was for features.

Yeah, but the problem is that it makes some things, like doing a quick 
debugging or profiling build, be a little more trouble than before. 
Since you need to either keep the separate build around (and you may not 
need it all the time), and remeber to reconfigure when a part of the 
build machinery has changed, or you have to re-run configure each time, 
which is a bit of a waste of time, if all you want to have is a some 
CFLAGS mixing.

cheers,
