You can declare variables either before or after the VA_OPEN,
- VA_FIXEDARG sequence. You can _not_ put statements before VA_OPEN.

- They must appear at the same nesting level, and any variables
- declared after VA_OPEN go out of scope at VA_CLOSE. Unfortunately,
- with a K+R compiler, that includes the argument list.

For ease of writing code which uses GCC extensions but needs to be
portable to other compilers, we provide the GCC_VERSION macro that
