It seems to work for me:
$ cat foo.c
#ifdef __STRICT_ANSI__
#error __STRICT_ANSI__
#endif
$ /usr/bin/cc -ansi foo.c
foo.c:2:2: #error __STRICT_ANSI__
The problem is it is also set for this:
$ /usr/bin/cc -std=c99 foo.c
foo.c:2:2: #error __STRICT_ANSI__
As you mentioned, this is now not a good test to decide if 'long long' is
supported.
