Can we instead replace 'sizeof ((expr) == 0)' with 'sizeof !(expr)'?
That works in C, and if it also works in C++ it would avoid the need
for the #ifdef __cplusplus.

It does not work in C++ because operator! could have been overloaded
or deleted.
OK, then how about 'sizeof ((expr) ? 1 : 0)'? This should work because ?: cannot be overloaded.
