12 // Optionally, the user may also define BENIGN_LANGOPT
13 // (for options that don't affect the construction of the AST in an
14 // incompatible way), ENUM_LANGOPT (for options that have enumeration,
15 // rather than unsigned, type), BENIGN_ENUM_LANGOPT (for benign
16 // options that have enumeration type), and VALUE_LANGOPT is a language option
17 // that describes a value rather than a flag.
