->On a different subject. Has anyone had problems with setbuf?
->I have a program that calls setbuf(stdin,NULL) and setbuf(stdout,NULL)
->to make a (b)yacc/bison parser work over a pipe. It works well under
->Linux, Solaris, and SunOS, regardless of whether the input comes from
->the terminal or the pipe. Under Win95, all goes well if I don't call
->setbuf, but then I can't use the pipe.

Sorry for the noise. This is explained in Cygnus's online documentation.
In summary, Cygnus's setbuf is non-standard; it seems that file I/O is
not buffered unless explicitly requested to be so with setbuf.
