PATHEXT is fundamental to Windows and Should be recognised by CYGWIN

Greetings, Michel LaBarre!
> Problem 1: Cygwin does not support PATHEXT and really should.
No, it should not. Cygwin is a POSIX environment, and it uses POSIX
conventions to determine if a file is executable somehow.
> PATHEXT is as fundamental component of Windows program execution as PATH.
PATHEXT is a shell (CMD) extension. Some programs do make use of it, notable
file managers and CMD replacements do, but overall, this is a mechanism of
finding the file to execute, not of executing it per se.
You can write your own extension to bash-completion "file-not-found" handler,
if you so desire.
> Problem 2: Cygwin does not support CR-LF delimiters.
Cygwin, in this case, is a library (newlib), and it doesn't care about
delimiters. This is an application's choice and right to support various EOL's

bash do cope, if you tell it to do. So does Cygwin, if you use text mounts.
Which is a sure way to destroy your data and cause lots of other messy

And they do run fine, as long as you are not making stupid mistakes, like
using bogus EOL terminators and expecting the program to work equally on
