[Qt-interest] Qt3_support removal

[Constantin Makshin]

You may try defining the "QT3_SUPPORT_WARNINGS" preprocessor macro — only  
add "DEFINES += QT3_SUPPORT_WARNINGS" to your Qt project file and  
re-generate makefiles. If you compile your program with GCC, you'll get  
warnings about used Qt3Support functions; I don't know how that macro  
works with other compilers.
