When installing e.g. Python via the Windows Store, it is common that the `python3.exe` entry in the `PATH` is not actually an executable at all, but an "app executaion alias" (i.e. a special class of reparse point).
These filesystem entries are presented as 0-size files, but they are not readable, which is why Cygwin has problems to execute them, with the error message "Permission denied". This issue has been reported a couple of times in the Git for Windows and in the MSYS2 project, and even in Cygwin (https://cygwin.com/pipermail/cygwin/2020-May/244969.html, the thread devolved into a discussion about Thunderbird vs Outlook before long, though). The second patch fixes that, and for good measure, the first patch teaches Cygwin to treat these reparse points as symbolic links.
