Re: warnings compiling Emacs 22 on amd64

[Richard Stallman]

    Some compilers support the use of #pragma directives to disable certain 
    warnings it would
    otherwise generate for the lines wrapped within those specific #pragma 
    directives.  Perhaps
    GCC could be extended to support this.

There's a big flaw in the design of #pragma: macros can't use it.  (It
is not recognized in macro expansions at all.)  In effect, the #pragma
interface is inadequate for just about any purpose that you might
imagine using it for.
