I took out the GNU extension trick (didn't even know it was a GNU

Yeah, emscripten is actually an LLVM backend, so actually under the hood
uses Clang as the compiler.
IMHO it's actually quite a good thing to be compiling with that even
aside from the JavaScript awesomeness :-) Clang seems to do a much more
thorough job when it comes to error messages than gcc seems to. I
actually committed a couple of trivial changes at the weekend to address
some warnings that were being flagged and I also then re-enabled -Werror
in the JavaScript CMakeLists.txt, so from now on compiler warnings are
going to fail the build. I personally think that's a good thing.
