Add -Wvarargs option
Several warnings related to questionable usage cases of variadic
function related macros (like va_start) could not be controlled by any
warning-related macro. Fixed thus, by introducing the -Wvarargs
option.
Tested on x86_64-unknown-linux-gnu against trunk.
gcc/c-family/
* c.opt (Wvarargs): Define new option.
gcc/
* builtins.c (fold_builtin_next_arg): Use OPT_Wvarargs as an
argument for the various warning_at calls.
gcc/doc/
* invoke.texi: Update the documentation.
gcc/testsuite/
* c-c++-common/Wvarargs.c: New test case.
* c-c++-common/Wvarargs-2.c: Likewise.
