program using the C skeleton (not lalr1.cc), tweaking the generated
code
to expand the parser stack regardless of __cplusplus, and compiling
with
C++ works in at least simple cases. What's the problem?
One problem is that the C stack does not call C++ copy constructors
when reallocating. So one can only use a POD semantic value.
But you have phrased is as an all through C program compiled as C++.
That must work if the C parser and the program is written in the
subset common to C++.
