The problem is that you're not getting shell arithmetic expansion. I'm
guessing that the shell invoked by your make (usually /bin/sh) is not
bash, or is one of the versions which doesn't support $[ ... ] for
arithmetic expansion (version 2.0 ?).

Try this to see if your shell does support $(( ... )) style expansion:
