[Might be an old idea from somewhere else, I just don't remember:]
1. Cygwin mount option "tmpfiles" to enable |FILE_ATTRIBUTE_TEMPORARY|
for all |open()|/openat()|/create()| which are opened for that
filesystem
2. Default /tmp mount (enabled by default), which just maps to
/cygdrive/c/cygwin64/tmp/, but has the "tmpfiles" mount option set

The idea is that opening files in /tmp will automagically set the
|FILE_ATTRIBUTE_TEMPORARY|

3. POSIX |tmpfile()| should open files with |FILE_ATTRIBUTE_TEMPORARY|
by default
