Hi,

Cool... I've just modified your code to correct case on $WINETC before we do the
directory check. This has the side-effect of catching the cygpath bug without
creating any links.

As for the script name, given the scope of /etc/postinstall I think it should
contain the package name. Someone suggested mketc.sh and that's fairly
consistent with the old-skool MKDEV script. So I think it should be called
cygwin-mketc.sh.

How come your script works when cygpath is called inside $(...) but not
backticks?

Paul
