re PR c/15444 (Bad warning message in printf format checking)
PR c/15444
* c-format.c (avoid_dollar_number): New function.
(check_format_info_main): Call avoid_dollar_number when operand
numbers might occur but has_operand_number == 0.
testsuite:
* gcc.dg/format/xopen-1.c: Adjust expected message.
* gcc.dg/format/xopen-3.c: New test.
