[Qt-interest] Qt 4.6.1 build bug with Cocoa (example included)

[André Somers]

I thought you could turn off the Qt keywords, and use Q_SLOTS instead? Try
to add this to your .pro file:
CONFIG += no_keywords

Note that all Qt signal/slot related keywords in your code will need to be
replaced with their macro counterparts:
slot -> Q_SLOT
slots -> Q_SLOTS
emit -> Q_EMIT
signals -> Q_SIGNALS / Q_SIGNAL

You can't call an array "slots" if you're using Qt.
