Add macros to control lemon diagnostics
Rename flex macros using parenthesis (mostly a style issue): DIAG_OFF_FLEX -> DIAG_OFF_FLEX() DIAG_ON_FLEX -> DIAG_ON_FLEX() Use the same kind of construct with lemon generated code using DIAG_OFF_LEMON() and DIAG_ON_LEMON(). Use %include and %code directives to enforce the desired order with generated code in the middle in between pragmas. Fix a clang-specific pragma to use DIAG_OFF_CLANG(). DIAG_OFF(unreachable-code) -> DIAG_OFF_CLANG(unreachable-code). Apparently GCC is ignoring the -Wunreachable flag, that's why it did not trigger an unknown pragma warning. From [1}: The -Wunreachable-code has been removed, because it was unstable: it relied on the optimizer, and so different versions of gcc would warn about different code. The compiler still accepts and ignores the command line option so that existing Makefiles are not broken. In some future release the option will be removed entirely. - Ian [1] https://gcc.gnu.org/legacy-ml/gcc-help/2011-05/msg00360.html
