You mean buffered?

Usually the libc decides if to use buffering by the fact if stdout is
atttached to a terminal (line buffering) or redirected to a file (full
buffering). Since -no-cygwin uses the MS libc, and MS libc doesn't know
anything about bash, I suppose they thing stdout is not connected to a
terminal when running under bash. This would at least explain this behaviour
and there would be nothing you can do about it, except using fflush (as a lot
of people already suggested).
