The problem is solved. 

It was caused by the presence of a previous QScintilla2 snapshot. The compiler 
picked up an include file (Qsci/qscintillabase.h) of that installation 
instead of the one in the 'Qsci' subdirectory of the sources. After deleting 
the include directory of the old installation compilation worked ok.
