Note that __STDC__ == 0 only when processing system header files; it will 
expand to 1 when processing user files.

I don't see the bug on the Solaris 9 box I have access to:

#include <sys/types.h>

int main(void)
{
  longlong_t i;
  return i._l[0];
}

poog% gcc -o test test.c
test.c: In function `main':
test.c:6: request for member `_l' in something not a structure or union

poog% gcc -D_NO_LONGLONG -o test test.c
poog%
