Subject: Use the configure script to enable/disable QtConcurrent and
 QtXmlPatterns

Using qglobal.h and checking the compiler version with the
preprocessor has the side-effect that moc won't generate proper code
since it doesn't know about the compiler version.

Enable both modules under Sun CC 5.9 and IBM xlC 7.0.
