Wow ... just wow.  That solves my problem completely.

I don't know what dark magic qmake employed to generate the better VCPROJ,
but this is so very cool.

I misunderstood (or forgot) the old-workflow:  Doing an
#include"moc_MyClass.cpp" in the bottom of my "MyClass.cpp" was all I
needed to get qmake to generate the proper "VCPROJ" that does not compile
the "moc_MyClass.cpp" separately.

(I couldn't find documentation to explicitly "suppress"
separate-compilation of the "moc_MyClass.cpp", but the "#include" was all I
needed.)

Thanks!
