.. for the record ...

Both 32-bits and 64-bits installations fail if one installs in the root of
a drive as result of a modification made by Ken Brown on 2019 09 25.

This statement also applies to:

 - https://cygwin.com/ml/cygwin/2020-01/msg00111.html
   ( Cygwin 3.1.X Fatal Errors - add_item ("\??\C:", "/", ...) failed, errno 22 )

Note: I am not saying that the modification made by Ken Brown is in error, but
that "something else" has to be changed as well ...
(init_cygheap::init_installation_root() in winsup/cygwin/cyheap.cc ?????)

Ken Brown's modification:

 - https://cygwin.com/git/gitweb.cgi?p=newlib-cygwin.git;a=commit;f=winsup/cygwin/path.cc;h=283cb372e4e25d1d11123d98e3d14e85b525e48d
   ( Cygwin: normalize_win32_path: improve error checking )

Item 2.5 of the FAQ advices NOT to install in the root of a drive (but it does
forbid to do so)

 - https://cygwin.com/faq.html#faq.setup.c

Item 2.5 ends with

"(In the past, there had been genuine bugs that would cause problems for people
 who installed in C:\, but we believe those are gone now.)"

This is no longer true: the past is back ...
