# If not compiling with C++11 (or later) support, all occurrences of "constexpr"
# must be replaced with "const", because "constexpr" is a keyword
# which pre-C++11 compilers do not support.
# ("constexpr" is needed in the code to perform in-class initialization
# of static non-integral member objects, i.e.:
#		static const double c_light = 2.99e8;
# which works in C++03 compilers, must be modified to:
#		static constexpr double c_light = 2.99e8;
# to work in C++11, but adding "constexpr" breaks C++03 compatibility.
# The following compiler flag defines a preprocessor macro which is
# simply:
#		#define constexpr const
# which replaces all instances of the text "constexpr" and replaces it
# with "const".
# This preserves functionality while only affecting very specific semantics.
