As this removes inaccurate information, it is OK.  It still leaves the
documentation a bit misleading, as the text only refers to C and the C
standard, leaving it silent about the languages supported.  By way of
comparison, the documentation of -Wparentheses only mentions C once and is
silent that all but one of the warnings are only implemented for C, not
C++.

I think C-family options should be clearly distinguished from more general
ones, and the C-family options should all make clear which languages are
supported; but if applicable and easy, it may be more useful to make both
front ends support an option and document that state of affairs, than to
document an existing arbitrary state of affairs.
