If you think a plainly labeled “Reporting Problems” and “Mailing Lists” in the prominent sidebar is difficult, then I’m afraid it’s only going to get worse from here.

“To you.” Almost every sentence in that paragraph should have “to you” at the end. I’ve used Cygwin for over a dozen years, and I have never once missed having PATHEXT in mintty/bash.
You can continue to use PATHEXT to your heart’s content in CMD.
Bash isn’t CMD.

“To you."

Yes it does, although it is heartily suggested they be left behind (pretty much any Windows program can handle Unix line endings but Notepad, and anyone using Notepad has bigger issues than line endings).
Text mounts can be created in Cygwin (although, again, not suggested). There are also a few (non-standard) things in Cygwin’s bash to try to handle CRLF scripts. You can search the archives for more information.

No, Cygwin _is_ a very smart supplement to that requirement. You talk as if Cygwin just showed up last week. It’s been around for almost twenty years, is widely used and widely respected.

> I disagree completely.  If you are in an interactive bash, running on a Windows computer, you sure as hell expect to be able to run "foo.bat" by typing "foo”.

No, _you_ expect to. I don’t. I know that Bash isn’t CMD.

Cygwin is providing a Posix environment on Windows. If you want a Windows environment on Windows, then use CMD. Almost all of Cygwin’s supplied programs work perfectly well in CMD, as long as you remember they’re providing a Posix environment and therefore need Unix paths, etc.
