Hmmm that's getting interesting :-)

Yes I agree. I recently had the intention to slightly lift up the makefile in order to separate several sets of options :

I decided not to do it because of the good old principle "if it's not broken, don't touch it". But if now we're certain it's already broken somewhere, here is a good opportunity to make a change.

Oh and by the way, to those who might wonder if it's why not switching over to autoconf, I can already reply that as an end user, I *hate* having to debug that complicated crap, and I don't want to impose it to any of my users ;-)
