- Several -Wshadow warnings - Several places where we did not initialize our base class explicitly - Unused variable warnings - Some tautological comparisons - Some places where we'd pass null arguments to functions expecting non-null (in unevaluated contexts) - Add a few pragmas to turn off spurious warnings - Fix warnings about declarations that don't declare anything - Properly disable deprecation warnings in ext/ tests (the pragmas we were using didn't work on GCC) - Disable include_as_c.sh.cpp because GCC complains about C++ flags when compiling as C. I couldn't find a way to fix this one properly, so I'm disabling the test. This isn't great, but at least we'll be able to enable warnings in the whole test suite with GCC.
