Nope, the mktest.out file is still wrong! Because $ENV{PERLIO} is explicitly
removed before testing, perl will run the tests with the default
PerlIO-layer(s) ('perlio' on most systems and 'perlio :crlf' on Windows).
The whole thing has always been a dirty hack (and I have happily hacked around
it again in the new Reporter.pm). The important thing is that the reports do
not suggest anything but standard environment. (There is the problem of
- -Uuseperlio in maint, where this does mean stdio)
I believe we now have a way to get to the PerlIO-layerstack from perl, but I
haven't looked into that.
good luck,
Abe
