yes, I reproduced your problem with ActiveState perl.

Indeed, you'll better report this to p5p.

OTOH as this is CORE module, why you need rebuilding it in the first place?

BTW when you will rebuild Perl on Win32 next time :), you'll edit "makedef.pl" first, to contain Perl_seed, so you'll have it exported next time :)
This way export functions are added.

But this bring me into misunderstanding a bit, how the Fine core perl built okay?
