It's irrelevent what the name of the .exe is.  As Igor already said,
even if a third party packages a cygwin1.dll that has simply been
renamed, it will still have the same shared memory name, so that if the
two DLLs are ever loaded at the same time they will clash.  This is
exactly what the error message you're getting indicates -- that you have
two incompatible Cygwin libraries on your system somewhere, even if one
of them has been renamed to something you don't recognise.
