You're still wrong.  Cygwin is a POSIX library for Windows.  Bash is a
shell capable of being built with that POSIX library for use on
Windows but it isn't an emulation of Bash, it *is* Bash.  Other shells
available on *nix is also available for Cygwin.

They don't need one in Cygwin either; as a matter of fact it was an
addition to binutils in the second generation of Cygwin that added the
.exe to the executable because it was more natural for Windows and
Windows at the time wouldn't execute the binary without the .exe

> Probably compiling binaries under cygwin without the exe extension, like unix, is not an alternative, or is it? Cygwin may detect if it is executable checking if it's PE format; if it is perl script.  Just check if file is present in path or run. /file

False.  It is wholly possible, you just have to pass the correct flags
to the linker process.  Current windows versions since at least XP and
maybe before would run files that did not contain a .exe extension.
