It frequently means I need to hack the configure script to build it. (And I do mean the configure script. Usually the developer is using a version of autoconf that I can't replicate.) Of course in my example case it is only a warning. But in general you can't count on that. > How does the user portably remove/override the -g and -O0 options?

Agreed. Bob
