One could hack something up in a plugin as a kind of workaround, but it 
would be sub-optimal. Maybe by handling Scintilla's sci-notify event to 
trigger off of modify and delete text notifications (ie. buffer 
changed), then do a pass over the buffer with GRegex, styling each match 

It would probably be quite slow if you opened massive source files but I 
did something similar before (for highlighting something else) and it 
wasn't noticeably slow on "normal" sized source code files IIRC.

Of course patching Scintilla's LexCPP.cxx to support styling function 
names would be much better. The Python lexer supports this for function 
definition names.
