My fault. Clang pays more attention to the file extension than to the driver
used. The correct output for C is:

test.c:1:9: error: initializer element is not a compile-time constant
int i = (struct s3 { int j; }) { 1 }.j;
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated

which makes the error clearer than in gcc because of the caret location and the
range (plus the beautiful colors ;-).
