ACK fails to remove some temporary files, uses weak permissions for temporary files, and may overwrite existing files with temporary files. I am looking for a better way to make...

In mach/i386/ncg/table, the EM patterns for `cmi 4` and `cmu 4` have wrong rules. They reverse the comparison, turning a < b into a > b. This is almost never...

I expect that `(a DIV b) * b + (a MOD b) = a` but our Modula-2 compiler fails me when `(a > 0)` and `(b < 0)`. It does...
