jperkin 0a552fe622 mk/compiler.mk: Support gnu++03 and c++03 in USE_LANGUAGES.
These can be used by packages when building with a compiler which defaults
to a newer standard than the source supports (e.g. namespace issues).

#
# This Makefile fragment implements handling for supported C/C++/Fortran
# compilers.
#
# The following variables may be set by the pkgsrc user in mk.conf:
#
# PKGSRC_COMPILER
# A list of values specifying the chain of compilers to be used by
# pkgsrc to build packages.
#
# Valid values are:
# ccc Compaq C Compilers (Tru64)
# ccache compiler cache (chainable)
# clang Clang C and Objective-C compiler
# distcc distributed C/C++ (chainable)
# f2c Fortran 77 to C compiler (chainable)
# icc Intel C++ Compiler (Linux)
# ido SGI IRIS Development Option cc (IRIX 5)
# gcc GNU
# hp HP-UX C/aC++ compilers
# mipspro Silicon Graphics, Inc. MIPSpro (n32/n64)
# mipspro-ucode Silicon Graphics, Inc. MIPSpro (o32)
# pcc Portable C Compiler
# sunpro Sun Microsystems, Inc. WorkShip/Forte/Sun
# ONE Studio
# xlc IBM's XL C/C++ compiler suite (Darwin/MacOSX)
#
# The default is "gcc". You can use ccache and/or distcc with
# an appropriate PKGSRC_COMPILER setting, e.g. "ccache distcc
# gcc". You can also use "f2c" to overlay the lang/f2c package
# over the C compiler instead of using the system Fortran
# compiler. The chain should always end in a real compiler.
# This should only be set in /etc/mk.conf.
#
# COMPILER_USE_SYMLINKS
# If set to yes, use symlinks for the compiler drivers, otherwise
# shell scripts are created. The default is yes.
#
# The following variables may be set by a package:
#
# USE_LANGUAGES
# Declares the languages used in the source code of the package.
# This is used to determine the correct compilers to make
# visible to the build environment, installing them if
# necessary. Flags such as --std=c++99 are also added.
# Valid values are: c, c99, c++, c++03, gnu++03, c++0x, gnu++0x,
# c++11, gnu++11, c++14, gnu++14, fortran, fortran77, java, objc,
# obj-c++, and ada. The default is "c".
#
# The above is partly aspirational. As an example c++11 does
# not force a new enough version of gcc.
# The following variables are defined, and available for testing in
# package Makefiles:
#
# CC_VERSION
# The compiler and version being used, e.g.,
#
# .include "../../mk/compiler.mk"
#
# .if !empty(CC_VERSION:Mgcc-3*)
# ...
# .endif
