* c-common.c (check_format_info): Properly save the argument
number and parameter for $ operand number formats in case width
and precision arguments are also used. Allow printf width and
precision arguments to have operand numbers even if none was
specified for the main format, since this is OK for %*.*m. Only
object to missing $ operand number if the format used requires an
argument.
testsuite:
* gcc.dg/format-ext-1.c: Add tests for mixing %m with $ formats.
* gcc.dg/format-xopen-1.c: Fix error in one $ format test. Add
more $ format tests.
