Hi.
If I remember correctly, "false" _is_ defined in ANSI C++. As I don't
have a documentation at hand, I cannot tell for sure, but a test run
suggests the same.
> cat test.cc
int main(int, char**)
{
bool flag = false;
}
> g++ --ansi --pedantic test.cc
runs without errors. (Note that it does not include anything, so
'false' is a recognized keyword.)
If I am right, this would mean that your xlC compiler either is not
standards compatible or you have to switch that on.
Bye,
Benjamin.
