OpenFst is a library for constructing, combining, optimizing, and
searching weighted finite-state transducers (FSTs). Weighted
finite-state transducers are automata where each transition has an input
label, an output label, and a weight. The more familiar finite-state
acceptor is represented as a transducer with each transition's input and
output label equal. Finite-state acceptors are used to represent sets of
strings (specifically, regular or rational sets); finite-state
transducers are used to represent binary relations between pairs of
strings (specifically, rational transductions). The weights can be used
to represent the cost of taking a particular transition.

FSTs have key applications in speech recognition and synthesis, machine
translation, optical character recognition, pattern matching, string
processing, machine learning, information extraction and retrieval among
others. Often a weighted transducer is used to represent a probabilistic
model (e.g., an n-gram model, pronunciation model). FSTs can be
optimized by determinization and minimization, models can be applied to
hypothesis sets (also represented as automata) or cascaded by
finite-state composition, and the best results can be selected by
shortest-path algorithms.

This library was developed by contributors from Google Research and
NYU's Courant Institute. It is intended to be comprehensive, flexible,
efficient and scale well to large problems. It has been extensively
tested. It is an open source project distributed under the Apache

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.

white lie, but it allows clang and gcc to be more similar
bump accordingly.
