Yes! This fixes the problem with scan.c not being found.

The next problem during "make check" is a g++ compilation failure:

  CXX      examples/c++/variant_11-variant-11.o
examples/c++/variant-11.cc: In member function ‘virtual int 
yy::parser::parse()’:

(YY_MOVE (yystack_[0].value.as < int > ()))); }
                                                             ^
