| in c_fully_fold. C_MAYBE_CONST_EXPR_PRE is the expression to |
| evaluate first, if not NULL; C_MAYBE_CONST_EXPR_EXPR is the main |
| expression. If C_MAYBE_CONST_EXPR_INT_OPERANDS is set then the |
| expression may be used in an unevaluated part of an integer |
| constant expression, but not in an evaluated part. If |
| C_MAYBE_CONST_EXPR_NON_CONST is set then the expression contains |
| something that cannot occur in an evaluated part of a constant |
| expression (or outside of sizeof in C90 mode); otherwise it does |
| not. */ |
