Regression in moc

There seems to be a regression in recent moc version (git describe - v5.1.1-1211-g3e346b8) where parsing signals in .h files with macros in front results in parse error. See attached testcase.

Fails when run like this:

moc -DKDE4SUPPORT_DEPRECATED= test.h

It used to work sometime before (not sure exactly) and it definitely works with Qt4 moc.

If you need any more information/testing, let me know.
