description         A portable foreign function interface library
long_description    The libffi library provides a portable, high level \
                    programming interface to various calling \
                    conventions. This allows a programmer to call any \
                    function specified by a call interface description \
                    at run-time.

# Don't use macports gcc or clang toolchains to build this due to dependency cycles

# Since libffi doesn't use C++, the cxx_stdlib setting is irrelevant, and
# having it differ from the OS default stdlib constrains the compiler selection,
# possibly even resulting in a circular dependency.  Hence, we clear the
# cxx_stdlib setting.
#
# Although libffi itself doesn't use C++, it provides support for the C++ ABI,
# and hence includes some tests written in C++.  The stdlib selection is not
# expected to impact libffi's own behavior, and if it did there would need to
# be appropriate conditional code to accommodate the difference.
#
# On the relevant OS versions (currently 10.6-10.8), this assumption can be
# tested by running the applicable port commands with
# "configure.cxx_stdlib=libc++".

# The architecture-detection code in the configure script is based on the
# compiler's default architecture.  We need to force this to match the
# target architecture to get the correct build.  Merely providing the
# correct architecture options in xxFLAGS is insufficient.
#
# This is a more general fix than the former fix for 10.6/ppc/Rosetta
