Can you guys add deprecation warning in qmake?

For instance, if I use QWorkspace instead of QMdiArea, you can warn me that the QWorkspace is deprecated, and recommend to use QMdiArea instead.

The reason is that I have been using QWorkspace since day 1, and never thought of it being deprecated until there is a problem. Of course I could have checked the document, but if someone is very familiar with a class, he will tend not to review the doc again and again. You never know, QMdiArea could be deprecated too in the future...

qmake will read the files anyway, so it knows which deprecated classes are in the codes...
