By default, gcc implements an extended C dialect. It supports many
things that are not standard C. It lists these extensions in its docs.

sroberts@pebble:/tmp% gcc -c -pedantic __.c
__.c: In function ‘foo’:
__.c:6: warning: ISO C90 forbids mixed declarations and code
sroberts@pebble:/tmp% cat __.c

int foo(void)
{
	int a;
	a = 0;
	int b;

	return a + b;
}
