           Summary: Request to add ability to disable inline/dllimport
                    warnings

I am working on ACE/TAO (www.cs.wustl.edu/~schmidt). With the upgrade to 
cygwin GCC 3.3.1 we get a lot of warnings that we use inline with dllimport 
and that attribute is ignored. Can an option be added to disable just this 
warning. I know I can disable all, but I want to keep the others. We have one 
codebase in which inlining can be disable by setting inline=0 in gnu make and 
I don't think we get all warnings gone because of the large number of 
combinations.
