The configure.ac template is -O0, and thus the configure script produced 
by autoconf is also -O0.

For the current Fedora and EPEL builds configure.ac is patched to -O2 as 
part of the build process.

We discussed at the community architecture planning meeting in July that 
going forward we would leave it -O0 for x.y.0 and x.y.1 releases and 
switch to -O2 for x.y.2 and later releases. (Although I haven't made 
that change for Fedora and EPEL yet.)

But note that for RPMs anyway, everything _is_ actually compiled with 
-g; the debug symbols are stripped from the binaries after the debuginfo 
RPM is produced. Off hand I'm not sure there's a lot of value in adding 
and --enable-debug option — just install the debuginfo RPMs instead if 
you want to debug.
