Hello Andre.  No I was mistaken.  the lower case didn't work at all.  It 
was blocking the build and I thought that it blocked the errors.

I'm not sure what you mean by having warn on in CONFIG.  I've installed 
the SDK with whatever the defaults were for the most part. I don't have 
-Wall set in the .pro file.

But if I add this line to the .pro file:
QMAKE_CXXFLAGS_WARN_ON += "-Wno-reorder"

this works.  It doesn't work setting QMAKE_CXXFLAGS though.
