I decided to uninstall Cygwin because, frankly, I don't use it that much and because the find_fast_cwd warning in the output of certain commands has been interfering with other programs which don't expect the warning in the output.
I confirmed that steps 1-3 here (http://www.cygwin.com/faq/faq.html#faq.setup.uninstall-all) don't apply, then uninstalled all packages via the setup utility. I deleted the Cygwin root directory and all shortcuts, although I left the setup utility and the downloaded files in my downloads directory for now. I checked the registry for all matches for "cyg" and deleted them, Software/Cygwin entries in particular, and I have no CYGWIN environment variable and PATH does not include the Cygwin directory. If I now enter Windows command prompt, commands like "ssh" and "cygcheck" are no longer valid and I get the appropriate error message. However, if I run commands like "ls" and "make" (included by other collections, such as MinGW), I continue to get the find_fast_cwd warning. I experimented a bit, and running "ls" in PowerShell, where it is a built-in alias, does not produce the error message as it does in command prompt, where it is not a built-in command. "make" is not built in to either one and produces the error message in both environments. What do I need to do in order to prevent this message from showing up again?
