AFAICT, install-sh should never be asked to install an executable which
lacks an .exe when the executable was built with a .exe extension.  So,
the fact that sometimes it "works" is a red herring.  As you noted, cp
has limited support for copying .exe files and mv has none.  It really
is up to gcc to accommodate that by specifying the .exe extension in all
cases.  That's the whole point of having an install-sh script.  It's
supposed to be accommodating of system pecularities.
