dev-lang/python/files/python-2.7.3-gcc-4_8.patch

Fix gcc 4.8 build broken for python 2.7.
The error was reported while building chromeos-chrome - "error:
'PyArg_ParseTuple' is an unrecognized format function type".  The issue is that
'-Wformat' is no longer included by default in gcc 4.8. The solution is to add
'-Wformat' explictly to configure.  For GCC 4.7, since '-Wformat' is enabled by
default, the modification has no impact to current gcc.  Below shows the
difference between gcc 4.7 and gcc 4.8.
   
     void f(char*,...)__attribute((format(PyArg_ParseTuple, 1, 2)));
     int
     main ()
     {
 
       ;
       return 0;
     }
 
     With gcc 4.7:
     $ gcc -Werror /tmp/foo.c
     /tmp/foo.c:1:1: error: ‘PyArg_ParseTuple’ is an unrecognized format function type [-Werror=format]
     cc1: all warnings being treated as errors
     $ echo $?
     1
    
     With gcc 4.8:
     $ ~/coding/gcc-python/gcc-svn-trunk/install/bin/gcc -Werror /tmp/foo.c
     $ echo $?
     0
    
     but on adding -Wall:
     $ ~/coding/gcc-python/gcc-svn-trunk/install/bin/gcc -Werror -Wall /tmp/foo.c
     /tmp/foo.c:1:1: error: ‘PyArg_ParseTuple’ is an unrecognized format function type [-Werror=format=]
      void f(char*,...)__attribute((format(PyArg_ParseTuple, 1, 2)));
      ^
     cc1: all warnings being treated as errors
     $ echo $?
     1
    
     or indeed just -Wformat:
    
     $ ~/coding/gcc-python/gcc-svn-trunk/install/bin/gcc -Werror -Wformat /tmp/foo.c
     /tmp/foo.c:1:1: error: ‘PyArg_ParseTuple’ is an unrecognized format function type [-Werror=format=]
      void f(char*,...)__attribute((format(PyArg_ParseTuple, 1, 2)));
      ^
     cc1: all warnings being treated as errors
     $ echo $?
     1
