-Wconversion

[Steven J Abner]

Hi
    I would like to use -Wconversion in building, however I've searched 
to find a way (like #pragma unused) to shut of the warning for a 
specific case.
    Example:
warning: passing arg 2 of 'chmod' with different width due to prototype
    I'm satisfied that there is no problem, so for the function or the 
location or completed source file that uses 'chmod' I'd like to stop the 
warning, but use a blanket flag -Wconversion for any new code created 
within a project or that source file.
    Is this possible? or is what I'm asking defeating the purpose? Is 
there a directive that I can place at the head of the source file that 
can be removed if new code is added?
    Thanks
