Although *nix system's try to figure out the interpreter for a script if
you don't provide it, it doesn't harm to do so. Thus, actually you
dont't have to distinct 2 cases here. We could simply use the MERGEMAP
you suggest for all currently supported systems.
However, i guess sooner or later we might need conditionals depending on
the OS. The easiest way to detect the OS running under *nix is the
command uname. On linux systems, the ouput is: Linux. Is that command
available in the cygwin environment ?
