<entry>Determines which compiler to use based on any given wishes.
Use <literal>c++11-lang</literal> if the port needs a C+11-capable
compiler, and <literal>c++11-lib</literal> if the port also needs
a C++11-ready standard library. If the port needs a compiler
understanding C11 or OpenMP, the corresponding parameters can be
used. Use <literal>features</literal> to request a list of features
supported by the default compiler. After including
<filename>bsd.port.pre.mk</filename> the port can inspect the results
using these variables:
<itemizedlist>
<listitem><para><varname>COMPILER_TYPE</varname>: the default
compiler on the system, either gcc or clang</para></listitem>
<listitem><para><varname>ALT_COMPILER_TYPE</varname>: the
alternative compiler on the system, either gcc or clang.
Only set if two compilers are present in the base
system.</para></listitem>
<listitem><para><varname>COMPILER_VERSION</varname>: the first two
digits of the version of the default
compiler.</para></listitem>
<listitem><para><varname>ALT_COMPILER_VERSION</varname>: the first
two digits of the version of the alternative compiler, if
present.</para></listitem>
<listitem><para><varname>CHOSEN_COMPILER_TYPE</varname>: the
chosen compiler, either gcc or clang</para></listitem>
<listitem><para><varname>COMPILER_FEATURES</varname>: the features
supported by the default compiler. It currently lists the
C++ library.</para></listitem>
