After all, this is likely why -fno-exceptions is not used with gcc and clang when compiling gtest. It would be a bit odd if exceptions were disabled for only Windows (More accurately VC) and not any other platform.

But `-fno-exceptions` *is* used for gcc (and probably for clang, though I've not checked). Verified by examination
of ".o.cmdline" files for both libgtest and the HotSpot gtests.
