AFAICS, the attached file should work (I've checked the workaround with other compilers), but BCB still doesn't like. Lacking the necessary BCB skills and tools, I'd appreciate if someone can take a look at it and, hopefully, turn it into a valid workaround for Borland. The relevant part is guarded by a "#if defined(__BORLANDC__)" directive.
Hi, the patch makes tupe_test_bench.cpp compile successfully on BCB 5.5.1 and 5.6.4. I have to add the disclaimer that it is an intuitive guess and may not be a real solution. I gave it a try, that's all ;+). The code looked good before I touched it and I have honestly no idea why my adjustments make BCB behave again (for both changes)... That this won't work: typedef typename boost::add_const<typename T::head_type> type; but this typedef typename T::head_type const type; is strange... Is there something wrong with add_const on BCB ??
