Your bison generated header also gets renamed by ylwrap, and yeah this
is probably the best place to ask about this problem your bison header
(y.tab.h) will get renamed to the same name as your bla.y but changed
to bla.h.

Notice the make line you posted was scgparser.cc y.tab.h scgparser.h
See the y.tab.h then scgparser.h.

Hope this helps!
