I mean that this is clearly a C90 violation.

Another question is whether some compilers accept parts of C99 but not
all of it.

As to the original problem, anonymous unions are a GCC extension, now in
C11 -- but not in C99:

barimba. echo 'struct { int a; struct { int b; }; } s;'|gcc --syntax-only -x c - -Wall -std=c99 -pedantic
<stdin>:1:34: warning: ISO C99 doesn’t support unnamed structs/unions [-pedantic]

So moving to C99 wouldn't help that.

Tom
