Interestingly though, C doesn't seem to allow an empty condition for while. 

$ cat a.c
int main() {
    while () { break; }
    return 0;
}

$ gcc a.c
a.c: In function ‘main’:
a.c:2: error: expected expression before ‘)’ token

It is well known to allow it for for. I read "for (;;)" as "for ever", and use it where some use while (1).

It could very well be unintentional, but fixing it could break code at no benefit.
