I concede to this interpretation for C++.

Note that the behavior for C/C99 also changed:

$ gcc-4.1.2 -std=c99 -Wall -pedantic x.c; ./a.out
x.c: In function ‘main’:
x.c:5: warning: type of bit-field ‘f’ is a GCC extension
x.c:8: warning: type of bit-field ‘f’ is a GCC extension
100000000 200000000 0
8000 0 0

$ gcc-4.4.0 -std=c99 -Wall -pedantic x.c; ./a.out
x.c: In function ‘main’:
x.c:5: warning: type of bit-field ‘f’ is a GCC extension
x.c:8: warning: type of bit-field ‘f’ is a GCC extension
100000000 0 0
8000 0 0

So apparently s.f doesn't promote to long anymore in C99.  Is this change in
behavior also intentional and correct?
