That makes senses to use O0. However, O3 is also the optimization  
option that turn on finline-functions and frename-registers, which  
makes debugging hard with gdb. O2 is fine here, and will be in most  
cases. It is generally admitted that O2 just works.

Anyway, I don't mind having a custom patch hanging in my configure.  
But don't you feel that --enable-debug should lower optimization by  
default? If so I'll patch configure to disable optimization by  
default if --enable-debug is on.

Alternatively we could override O3 parameters when debugging, so that  
gcc can produce debug-able binaries.

What are your thoughts on that?

Pierre.
