Right, and people know about that from reading their user manuals.

RE: Turning warning off

[Young, Michael]

I went to look in the documentation for this, because I am interested, too.  
I did see section 3.8 - "Options to Request or Suppress Warnings", but I did not find exactly what I was hoping for.  Specifically, I'm looking for a way to turn off a specific warning inline, with the ability to restore it again - analogous to the #pragma warning directive supported in MS VC++ (see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang/html/_predir_warning.asp for details).
I did a web search for this, too, and found that others have asked similar questions, but never found a definitive answer.  Based on this, I would assume that the answer is "no, the functionality you're looking for is not implemented in gcc".
Does anyone know anything contrary to this?

I'm not sure about that warning.  Better to mark the register
__attribute__((unused)).

Lots of compilers have the ability to turn off a particular warning
message, does Gcc?
Because I am setting and not "using" a register (bread crumb)  until a
reset occurs I get a warning message about value not being used.
I can add a note in code but it would be better that I could add something
to code to prevent this known (and acceptable warning)
