No amount of checking with the Perl community is likely to resolve this
quickly w.r.t. existing releases of Perl.

We seem to have a choice either to abandon, at least temporarily, perl
support on Windows for versions of perl >= 5.20 (I think) or adopt the
suggestion I made. It's not a complete hack - it's something at least
somewhat blessed in perl's XSUB.h:
   /* dXSBOOTARGSNOVERCHK has no API in xsubpp to choose it so do   #undef dXSBOOTARGSXSAPIVERCHK   #define
dXSBOOTARGSXSAPIVERCHKdXSBOOTARGSNOVERCHK */
 


Note that on earlier versions of perl we got by without this check for
years without any issue or complaint I recall hearing of. If we don't
adopt this I would not be at all surprised to see Windows packagers
adopt it anyway.

cheers
