And it would be cool if 3 enables me to use "feature.set-default address-model : 64" on Windows 64 bit machines to enforce 64 bit builds as default.

I've tried this way but it quickly gets dirty as soon as one gets both "header-only" and library. So -2 for this solution. Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold ! * voice: ++49 4257 300 !
