// Prevents symbols from being substituted by the corresponding macro definition
// under the same name. For instance, min and max are defined as macros on
// Windows (unless NOMINMAX is defined) which causes compilation errors when
// defining or referencing symbols under the same name.
//
// To be robust in all cases particularly when NOMINMAX cannot be used, use this
// macro to annotate min/max declarations/definitions. Examples:
//
// int max CERES_PREVENT_MACRO_SUBSTITUTION();
// min CERES_PREVENT_MACRO_SUBSTITUTION(a, b);
// max CERES_PREVENT_MACRO_SUBSTITUTION(a, b);
//
// NOTE: In case the symbols for which the substitution must be prevented are
// used within another macro, the substitution must be inhibited using parens as
//
// (std::numerical_limits<double>::max)()
//
// since the helper macro will not work here. Do not use this technique in
// general case, because it will prevent argument-dependent lookup (ADL).
