DescriptionMiniSat is a minimalistic, open-source Boolean satisfiability problem
(SAT) solver, developed to help researchers and developers alike to get
started on SAT.
Some key features of MiniSat:

* Easy to modify. MiniSat is small and well-documented, and possibly
also well-designed, making it an ideal starting point for adapting SAT
based techniques to domain specific problems.
* Highly efficient. Winning all the industrial categories of the SAT
2005 competition, MiniSat is a good starting point both for future
research in SAT, and for applications using SAT.
* Designed for integration. MiniSat supports incremental SAT and has
mechanisms for adding non-clausal constraints. By virtue of being easy
to modify, it is a good choice for integrating as a backend to another
tool, such as a model checker or a more generic constraint solver.

The OpenBSD package of MiniSAT installs two binaries:
minisat_core = A core version of the solver.
minisat = An extended solver with simplification capabilities.

CVS Commit History:

Log message:
Add COMPILER lines to c++ ports which currently use the default. Adjust
some existing COMPILER lines with arch restrictions etc. In the usual
case this is now using "COMPILER = base-clang ports-gcc base-gcc" on
ports with c++ libraries in WANTLIB.
This is basically intended to be a noop on architectures using clang
as the system compiler, but help with other architectures where we
currently have many ports knocked out due to building with an unsuitable
compiler -
- some ports require c++11/newer so the GCC version in base that is used
on these archirtectures is too old.
- some ports have conflicts where an executable is built with one compiler
(e.g. gcc from base) but a library dependency is built with a different
one (e.g. gcc from ports), resulted in mixing incompatible libraries in the
same address space.
devel/gmp is intentionally skipped as it's on the path to building gcc -
the c++ library there is unused in ports (and not built by default upstream)
so intending to disable building gmpcxx in a future commit.
