But even without this patch, the ACK compiler is a no-go for three reasons:

1) It does not support 'long long'.

2) It has serious problems with array types.

3) It chokes on valid code that ought to produce a division by zero at runtime:

Thomas, can you please report these compiler bugs to the ACK maintainers?
