Just to be clear: *my* point is that on OS X those variables are basically ignored during a Qt build.

Indeed.

Progress report: using my trick of pre-filling a .qmake.stash file in build/qtbase let the build process continue for hours without a glitch *). Until it hit the -Wno-c++* options used for building QtWebkit; turns out QtWebkit found a way to thwart my mkspec and use an Xcode compiler ...


*) 1 probable bug: one of the geoclue files does `value = new GValue; *value = GVALUE_INIT;`. Apparently that passes Apple's clang and gcc, despite the explicit warning above the GVALUE_INIT macro definition that it cannot be used to initialise variables except when they're being declared. Stock clang-3.5 apparently agrees, so I had to do `memset(value,0,sizeof(GValue))`.
