removed fflush calls in Bison

[Paul Eggert]

I installed this:

2002-12-28  Paul Eggert  <address@hidden>

        * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
        fatal): Don't invoke fflush; it's not needed and it might even be
        harmful for stdout, as stdout might not be open.
        * src/reduce.c (reduce_print): Likewise.
