Yes.  In the perl source is defined if a system that defines O_TEXT
with a different value as O_BINARY kind of DOSISH, then the :crlf
PerlIO layer will be used.  That is to override the default :stdio
layer (as it is on unix).  If I change it to be Cygwin != DOSISH, then
the standard Unix layer :stdio will be used if no environmet setting
overrides it and every other layer like e.g. :perlio, :crlf or :utf8
may be pulled in by request. 
I think this is what we want.
