This is a good idea, but there might be one caveat.  What does "echo $0" 
print on your machine, exactly?  Specifically, does it use forward- or
back-slashes?  If it uses back-slashes, Bash (or Make) could choke on 
such a name when it is later used.

Whether the $0 is printed with backslashes or not depends on many 
installation-dependent details.  So I suggest to pass $0 through a simple 
Sed script that explicitly converts any \ into /, before assigning it to 
CONFIG_SHELL.
