Sure.
My question is how to interperate the code, since I don't understand its
syntax.
If it is a C99 code, what's the C99 feature for it ?
Thanks.
Mike

I believe this is standard C99 code, not a gcc extension. It's a gcc
extension to accept this in C90 mode.
I don't really understand what your question means, anyhow. Can you
rephrase?

void foo() {
if(
( __extension__
(
(
(
union {
int a;
int b;
}
) { .a =7 }
) .b
)
) == 7 ) {
printf("abc\n");
}else {
printf("def\n");
}
}
int main() {
foo();
}
