Roderich,
I tried the pp command with the --link libpng16-16__.dll option and
found libpng16-16__.dll included with the executable (it definitely
wasn't without the --link option) but running the executable on a
Windows 10 machine with no Perl installed produced exactly the same error.
It seems to me that e88b1fb1.xs.dll is some kind of dynamic file which
gets created if Perl is installed but not if there is no Perl.
