One possible solution to distinguish between signals and normal methods is to 
define the macro signal (or Q_SIGNAL, if QT_NO_KEYWORDS is defined) as a 
gccxml attribute. Same for slots.
Another possibility is to run moc over the sources and parse the generated cpp 
file. This sounds harder and uglier, though.
I don't know about the syntax errors. I've not yet tried to compile the Qt 
sources with gccxml.

Hope that helps,
