I'm not compiling this for distribution, so is there any reason not to change "-mtune=generic" in the two lines above to "-mtune=native"?  (The latter is what "man gcc" actually recommends.)

Anyone have insight into this first issue?  I don't see how changing the 
target cpu for compiling could possibly muck up the outcome.  But I'm 
not at all familiar with QScintilla.
