FYI, the shell that make will use, by default, in a normal Cygwin
installation is 'ash' (aka /bin/sh), not 'bash'.

Cygwin's stat() function has historically always found a 'foo.exe' when

I'm sure that you can find many many many similar observations of this

It's long standing behavior. I have no idea what would break if we
