Ah.... actually they do use that workaround when we define those types 
ourselves... but on most platforms we simply include the platform's stdint.h 
so we have no real control over those definitions :-(

So the only suggestion I have is to add a 
<toolset>gcc:<cxxflags>-Wno-long-long to your usage requirements.

HTH, John.
