| I am not sure whether the correct one is OPT_Wcxx0x_compat or
| OPT_Wc__0x_compat.
OPT_Wc__0x_compat
See the output of the automatically generated header out of c.opt.

Please be aware that if you introduce redundancies you have to check
consistency. If you make the system orthogonal, you just need to
compose.
