I guess we are reading very disjoint sets of lists, then ;-)

Both true and false.  The issue here is not whether to prefer Cygwin
over MinGW.  The issue is whether it is a good idea to have a MinGW
build of Emacs use Cygwin ls to produce directory listings on which
the MinGW built Emacs will have to operate.  IOW, the issue is mixing
Cygwin and MinGW programs in the same workflow, when it is known that
the way each one represents Posix access bits is radically different.
