YACC STACK OVERFLOWS

The preprocessor symbol BUG_TOOBIG controls compilation of code we had to insert to avoid "yacc stack overflow" errors in the SunOS 3.5 C compiler. Release 2.0 produces very complicated expressions for the inline copy constructors it generates for deeply-derived classes. Explicitly defining non-inline copy constructors solves the problem. If you are a C compiler vendor, please make your tables big enough to handle the C code generated by the AT&T C++ Translator!
