Comment(by anonymous):

 The problem I have with this patch, is that it disables this warning
 permanently - including in user code.  Also the gcc docs say:

 "Note that these pragmas override any command line options. Also, while it
 is syntactically valid to put these pragmas anywhere in your sources, the
 only supported location for them is before any data or functions are
 defined. "

 So basically you can only use these at the top of the source file
 ''before'' any #includes, and not in a header?

 IMO we need a different fix... #pragma GCC system_header maybe?

 John.
