Fix: Cygwin make fails after updating to bash v 4.1.9.2

Extracts from the cygwin Bash 4.1.9.2 release announcement:

4a. For a single affected script, add this line just after the she-bang:
 (set -o igncr) 2>/dev/null && set -o igncr; # comment is needed

4e. bash-4.1.9-1 dropped support for 'shopt -s igncr';

I'm assuming this is backwards compatible; If not, we'll know quite shortly :)
