How is changing bash going to do anything?  The kernel takes
care of executing files with a `#!' magic number.  I presume
that the cygwin dll handles this.

There is an incompatibility between the linux kernel and other
Unices in the way they parse arguments after the interpreter
name, but that's not really bash's business.
