Also, VA_OPEN and VA_CLOSE are the beginning + and end of a block. 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. You can have multiple instances of VA_OPEN/VA_CLOSE + pairs in a single function in case you need to traverse the + argument list more than once. + + For ease of writing code which uses GCC extensions but needs to be + portable to other compilers, we provide the GCC_VERSION macro that + simplifies testing __GNUC__ and __GNUC_MINOR__ together, and various + wrappers around __attribute__. Also, __extension__ will be #defined + to nothing if it doesn't work.
