To the original poster, in case you couldn't make any sense of that, the
english translation is: Current versions of Cygwin1.dll are
backwards-compatible but older versions of Cygwin1.dll are not
forwards-compatible, nor would it be possible for them to be.
Running older versions of the DLL is not supported, as you would have to
downgrade every other package on your system to a state that would
maintain binary compatibility. It would be theoretically possible, of
course, but you'd have to work out which versions of the DLL each
package was compiled against and then hunt down enough previous versions
of all those packages to satisfy those dependencies.
