* utils/hbmk2/hbmk2.prg
- Deleted supc++ lib. hbmk2 won't be able to solve every existing
compiler configuration problems, so in this case users will have to deal
with this special case and supply supc++ or supcxx or stdc++
lib if it's required, or manually select C++ mode for hbmk2 if
that better solves local needs.
Case closed from my side.
