[ocaml-platform] [Caml-list] Package compilation and debug mode

How do you envision such a global debug flag? As far as I know, there is no configuration-time option to enable that option in the compiler (which would be the cleaner option IMHO). I'd rather avoid using OCAMLPARAM for this. A new opam variable can be created and used in the opam file to pass the debug command (or not) explicitly to the build system, but this will require adapting all the build systems (and ideally a new release of opam, but we can work-around that by setting OPAMVAR_debug in the .comp file).

I don't have a strong opinion either. I like when packages come with -g by default, but I can understand that the (small) runtime cost can be a problem for deployment scenarios.
