Some compilers (MS VisualStudio at least) throw a warning "unreachable
code" on this part of the parser:
yyerrorlab:
/* Pacify compilers like GCC when the user code never invokes
YYERROR and the label yyerrorlab therefore never appears in user
code. */
if (false)
goto yyerrorlab;
That's correct, the code is unreachable, so we have one warning replaced
with another. I'm afraid that inclusion of this code has to be made
conditional depending on whether YYERROR is acutally used anywhere.
