Good morning Anton,
Sorry for being brief (and not being clear!).
(and sorry for being late to the party :-)
What I meant, was: a regular file (empty or not), but w/o shebang and w/o the
execute bit, will be executed by Cygwin, contrary to what happens on Unix.
This behaviour (again: different from Unix) has existed for at least a decade.
That is why I wrote: Cygwin != Linux.
When I found out, years and years ago, I assumed that the deviation was due
to FAT filesystems (not being able to represent the x-bit).
Perhaps I was wrong. Perhaps the Cygwin maintainers merely goofed up long ago.
Henri
