Setting CONFIG -= warn_on in the pro file suppresses all warnings.
Where can I see the settings in CONFIG?

I think I see what's happening.

With
  QMAKE_CXXFLAGS_WARN_ON += "-Wno-reorder"
QMAKE_CXXFLAGS_WARN_ON += "-Wno-unused-parameter"

in my pro file, a typical line looks like this:

g++ -c -pipe -g -Wall -W -Wno-reorder -Wno-unused-parameter -D_REENTRANT 
-DQT_GUI_LIB
...

With
QMAKE_CXXFLAGS += "-Wno-reorder"
QMAKE_CXXFLAGS += "-Wno-unused-parameter"

a typical line looks like this:

g++ -c -pipe -Wno-reorder -Wno-unused-parameter -g -Wall -W -D_REENTRANT 
-DQT_GUI_LIB
...


For some reason, in this case, the -Wall is after the first two. Not 
sure why that would be the case but it seems like that's the problem.
