Broadening the question, does the cygwin community have advice on the
best implementation of a function that returns true if the argument is a
uid with full privileges (for example, if the uid is a member of the
Administrator group, and can therefore read files in spite of chown()
disabling all the read permissions)?  We're trying to improve gnulib
(and therefore coreutils, findutils, tar, ...) to use an
implementation-appropriate check rather than the more traditional
hard-coded check of uid==0, since that doesn't quite work everywhere.
