OK, I agree that *-*-cygwin* should not appear in this list since it
should be using dlopen, not LoadLibrary.

The context for this code snippet is:

  if $dlopen_api || $shl_load_api || $loadlibrary_api || $dyld_api; then
    true
  else
    case "$canonical_host_type" in
      *-*-cygwin* | *-*-mingw* | *-*-msdosmsvc)
       loadlibrary_api=true;
      ;;
    esac
  fi

so I still don't understand why the test for dlopen_api is failing for
you.  Can you please post the relevant parts of the config.log file
that show the results of the checks for the dlopen, dlclose, dlerror,
and dlsym functions?
