[gnugo-devel] no line buffering on stdout for ascii and gtp mode.

[Teun Burgers]

Current CVS does not display a prompt when expected
in both gtp and ascii mode, for both cygwin and mingw.
The prompt only comes after commands have been entered.
I suspect this is because the prompt does not contain a newline and
hence linebuffering does not display the prompt.

For ascii mode this is fixed by setting buffering
to _IONBF. For gtp mode this does not help.

- No buffering on stdout in ascii and gtp mode.
