Well, ... there is no proper way to what you want with make, or at least
it would be of very doubtful wealth.

As far as permissions are concerned, the most simple work-around would
be:
chmod -R +w <sourcedir>

As far as dos textfiles are concerned:
find <sourcedir> -type f -exec dos2unix {} \;

IMO, you are playing with symptoms. The actual fix to issues like these
is to use editors which do not store unix-files in DOS mode.

IIRC, you also should mount the partition containing the sources binary,
otherwise some Cygwin text-utils will convert them to DOS-text-files.
