Hi, One thing is not clear for me. What are these switches doing on non-Intel systems?
Next thing to decide is how to control this matter, because if you say that hbmk2 should automatically add -m64 as linker option, it means we're converting -m* switches to hbmk2 ones, and in this case I'm not sure it's the best thing to do. We already have -plat switch to choose these kind of things for win/wce platform, but it's not very good either, so maybe its time to introduce new -cpu switch. This however seems to need more serious redesign of autodetection code in hbmk2 and possibly in GNU Make system (and probably more). So for now, to avoid that, the best shortcut is to simply parse HB_USER_CFLAGS for -m64/-m32 and make some internal decisions based on that. It cannot be done in very clean way, but at least I don't have to rewrite the whole thing before release. In this scenario it's users job to pass this switch to HB_USER_LDFLAGS also (but is this really required?, cannot the linker automatically detect the target arch based on input files?). The other remaining thing to see, is how this thing works on other *nix platforms? bsd for example, or even darwin. On darwin / clang and gcc it seems to work similarly to Linux, but I did only try on Snow Leopard / Intel.
