1350 operands are real constants, call fold_relational_const. If either
1351 operand is a NaN, evaluate the other for side-effects and return a
1352 constant. Optimize (double)float1 CMP (double)float2 into the
1353 equivalent float1 CMP float2.

9827 requested to compile more than one file at once. (This disables
9828 IMA temporarily - an up-front error being preferable to a crash.)
9829 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
9830 (all actions): Adjust calls to pushlevel/poplevel.
9831 (parsing_iso_function_signature): Delete.

14614 (_cpp_lex_direct): Use linemap_position_for_column.
14615 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
