-Werror is generally suppressed in Bison-generated C/C++ code (as in all other generated code) to silence warnings from the Bison skeleton code. And the Clang plugins suppress warnings in generated WORKDIR code based on the presumed source location (i.e., taking #line directives into account). So introduce a new PLUGIN_WARNINGS_AS_ERRORS mode where warnings from Clang plugins are reported as errors even if -Werror is suppressed. That way, any warnings in the Bison skeleton code still do not lead to compilation errors, while (at least plugin- emitted) warnings in the genuine source code do. Unfortunately this cannot also be enabled for Flex source code, as at least Flex 2.5.39 generates poor code that does not properly prefix all skeleton code with appropriate #line directives, so that some skeleton code would be mistaken for genunie source code, and compilation would fail due to errors. Also, %glr-parser Bison input appears to generate no #line directives at all (at least with Bison 3.0.4), so all of connectivity/source/parse/sqlbison.y is considered generated code and plugin warnings are still suppressed throughout.
