add_constant()

struct md_constant * add_constant ( htab_t defs, char * name, char * value, struct enum_type * parent_enum )

static

Add a NAME = VALUE definition to md_constants-style hash table DEFS,
where both NAME and VALUE are malloc()ed strings.  PARENT_ENUM is the
enum to which NAME belongs, or null if NAME is a stand-alone constant.
