10// This file defines the language options. Users of this file must
11// define the LANGOPT macro to make use of this information. 
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.
