One interesting test case may be to remove the x bit from the empty bash 
file, to see that mintty handles invocation errors properly.
The issue is that invocation of an empty file (provided that the x bit 
is set) is not considered an error in a Linux environment, and thus on 
cygwin, so the exec system call does not report an error in the first place.
There is nothing that can be done about it, the behaviour is correct.
