[Samba] Building with debug symbols and different optimisation levels

[Edward Robbins]

Hello,
I would like to build samba at different optimisation levels with debug
symbols, in order to test a static analysis tool I have developed. I have
found the configure option "--enable-developer", which I presume enables
debug symbols and sets optimisation to O0, and "--enable-debug" (is the
difference between these two options just the warning levels?), however I
would also like to be able to enable debug symbols and set the optimisation
level to O2.

I've been searching but cannot find a way to do this in the build system, I
can't even find where the optimisation level is set, however, I am
unfamiliar with waf. Is there a (even hacky) way to do this?

Thanks,
Ed
