I find it a bit ironic that Clang does inform the user when something is
accepted as a GNU extension, but *GNU* GCC does not clarify this. Perhaps the
pedwarn below would be clearer with something like?
warning: narrowing conversion of '(double)u' from 'double' to 'int' inside { }
is a GNU extension
Or even something fancier:
warning: narrowing conversion of '(double)u' from 'double' to 'int' inside { }
(error in c++11, allowed by gnu++11)
or
warning: (GNU extension to c++11) narrowing conversion of '(double)u' from
'double' to 'int' inside { }
It would be not too difficult to automatically print the current base standard
and the corresponding gnu standard on every pedwarn.
