Enforce translation mode for Windows frontends to text with open/fopen
Allowing frontends to use concurrent-safe open() and fopen() via
0ba06e0
has the side-effect of switching the default translation mode from text
to binary, so the switch can cause breakages for frontend tools when the
caller of those new versions specifies neither binary and text. This
commit makes sure to maintain strict compatibility with past versions,
so as no frontends should see a difference when upgrading.
