[cfe-commits] [patch] Fixing warnings in libc++'s locale header

[Dimitry Andric]

Hi,

This fixes a few warnings that occur in libc++'s headers, when building
with -Wsystem-headers:

In file included from /usr/include/c++/v1/iostream:40:
In file included from /usr/include/c++/v1/istream:156:
In file included from /usr/include/c++/v1/ostream:132:
/usr/include/c++/v1/locale:2878:25: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces]
         {pattern __p = {symbol, sign, none, value}; return __p;}
                         ^~~~~~~~~~~~~~~~~~~~~~~~~
/usr/include/c++/v1/locale:2880:25: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces]
         {pattern __p = {symbol, sign, none, value}; return __p;}
                         ^~~~~~~~~~~~~~~~~~~~~~~~~
/usr/include/c++/v1/locale:3194:35: error: unused variable '__et' [-Werror,-Wunused-variable]
                 ios_base::iostate __et = ios_base::goodbit;
                                   ^

The first two warnings are because money_base::pattern is declared as a
struct containing a char array, so the char array itself needs
additional braces.

The third warning is because r152501 changed some code in __do_get()'s
money_base::symbol case, which made the __et variable unnecessary.
