i've been using cygwin/x for many years and i did an installation to a new
computer and when i try to start xwin i get a popup windows with the
following error message:

LoadLibrary failed with error 87: the parameter is incorrect.

i start xwin with the following command line:

startxwin -- -clipboard -silent-dup-error -listen tcp

and get the following output:
