Warning: you don't want to compile your libraries without -g, or your
users won't be able to debug fully (even if they use -g for their own
code, the lack of -g in the libraries will mean, for instance, that
the debugger things iostreams, strings, etc are unknown classes).

You don't need to edit the makefiles; it suffices to say, for example
make CFLAGS=-O2
