Subject: Use (file PerlIO::Layer 'perlio') rather than $Config{useperlio}
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=6b5da1a3dd326d0fe0f59ec1ea7b9b5d72b2a49e;p=p5sagit%2Fp5-mst-13.2.git

Use (file PerlIO::Layer 'perlio') rather than $Config{useperlio}
as gate on layer tests which fail on -Dusesfio
(ext/XS/Typemap/Typemap.t still fails on -Dusesfio)
