# $FreeBSD$
# Setup variables for the compiler
#
# COMPILER_TYPE is the major type of compiler. Currently gcc and clang support
# automatic detection. Other compiler types can be shoe-horned in, but require
# explicit setting of the compiler type. The compiler type can also be set
# explicitly if, say, you install gcc as clang...
#
# COMPILER_VERSION is a numeric constant equal to:
# major * 10000 + minor * 100 + tiny
# It too can be overriden on the command line. When testing it, be sure to
# make sure that you are limiting the test to a specific compiler. Testing
# against 30300 for gcc likely isn't what you wanted (since versions of gcc
# prior to 4.2 likely have no prayer of working).
#
# COMPILER_FEATURES will contain one or more of the following, based on
# compiler support for that feature:
#
# - c++11 : supports full (or nearly full) C++11 programming environment.
#
# This file may be included multiple times, but only has effect the first time.
