  Message : Fixed more warnings. Clang warns about missing case in enum glslang_lex.cpp so I disabled that one as well. MSVC, as Chromium is built at least, warns about things in its own STL headers in SymbolTable.cpp so disabled the warning for that file. esTransform.c had a struct that the compiler could not determine was initialized so I explicitly initialized it.
