 Hi there,
 
 I will try to make one tomorrow.  If not, it'll have to wait until a few 
 weeks from now since I'm about to leave for a trip.

 From the info file of gcc:
 `-Wno-deprecated (C++ only)'
      Do not warn about usage of deprecated features.  *Note Deprecated
      Features::.
 
 I.e. -Wno-deprecated is C++ only and for me g++ rejects the sample
 code with a syntax error. So this works as advertised.

 Attached is a very simple testcase, which demonstrates the problem quite
 well.

>Description:
Even when compiling with -Wno-deprecated, gcc will spew warnings about many deprecated features, such as concatenating __FUNCTION__ with a string.  This makes it very hard to migrate to using a newer gcc, since all these warnings are likely to hide real bugs.  It would therefore be desirable if -Wno-deprecated would genuinely suppress warnings about deprecated features, *or* add a -Wno-all-deprecated or some such option.
