Does "console code page" issue apply to MinGW, Cygwin builds?

At the bottom of
http://developer.postgresql.org/docs/postgres/install-win32.html
there is some info about having to set the correct console code page
for psql.  Does this apply to the MinGW and/or Cygwin builds, or is it
only relevant for Visual C++ and Borland C++ builds?  If the former,
it's in the wrong place.  I am not sure what the right place is though.
