re PR c/13282 (A "-Wno..." switch to turn off "missing initializer" warnings)
PR c/13282
* c.opt (Wmissing-field-initializers): New option.
* c-opts.c (c_common_post_options): Make -Wextra turn it on by default.
* c-typeck.c (pop_init_level): Guard the missing field warning with
warn_missing_field_initializers rather than extra_warnings.
* doc/invoke.texi (-Wmissing-field-initializers): Document, moving
some of the explanation from...
(-Wextra): ...here. Say that the missing field warning can be
seperately controlled by -Wmissing-field-initializers.
cp/
* typeck2.c (process_init_constructor): Guard the missing field warning
with warn_missing_field_initializers rather than extra_warnings.
testsuite/
* gcc.dg/missing-field-init-[12].c: New tests.
* g++.dg/warn/missing-field-init-[12].C: New tests.
