create a testParser.cpp file which consists of 1 line
#include "testParser.c"
When your project compiles testParser.cpp the generated code for declaring
flag will work.
NOTE: you cannot use the variable flag in any predicate or production
before the first token is consumed.
code before the first token may be "hoisted" into the parent rule
and the local variable flag will
not be defined in the parent rule context.
