X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8aedf199e986fffd4372cc9106e32f19709d7e87;p=clang

Fix PR2281: these two warnings should be promoted to error on
pedantic error.  Perhaps I should add a class of 'extension' that is
'extension that warns by default', which would be cleaner.
