PR preprocessor/16950: [3.5 regression]: -Wno-deprecated doesn't work

[H. J. Lu]

Hi DJ,

Could you please take a look at it? Your patch:

http://gcc.gnu.org/ml/gcc/2004-06/msg01541.html

removed setting of warn_deprecated in c_common_handle_option in
c-opts.c. It isn't set anywhere in gcc. But it seems that before 
Aug. 6, 2004, __DEPRECATED was defined when -Wno-deprecated was
used. But today, __DEPRECATED is always defined due to

      if (warn_deprecated)
        cpp_define (pfile, "__DEPRECATED");

in c_cpp_builtins in c-cppbuiltin.c.
