Define JNIEXPORT as visibility default with GCC?

Another rev of this change.
I added the condition check for gcc > 4.2
(I don't much care either way)

I just ran "clang" for the first time, and was surprised that clang has
values of __GNUC__ == 4 and __GNUC_MINOR__ == 2

I think we should keep the __has_attribute check, because it seems clearly
correct and recommended by
and with luck, __has_attribute will become a minor industry standard from
the innovators in llvm-land.
I really like the design of their extension mechanisms.
