Hi Eric,
The 'e1' variable is not needed, I think. No standard specifies that errno
must be preserved across function calls:
- C99 does not mention 'errno' in the description of fflush,

Anyway, for what it's worth I think fflush (stdin) should behave like
1988 POSIX and glibc, at least for apps that care about this sort of
thing.
Here's my first attempt at this. I don't have easy

Hi Eric,
Hi Gary, and adding gnulib readers,
Yuck. I think this means that on your platform, fflush(stdin) is
neglecting to reset the underlying fd position when stdin is seekable,
which is a

Here is the relevant code from modules/m4.c in CVS HEAD:

At worst we need an autoconf test to see whether fflush works on stdin,
but maybe all that is needed is to call fpurge when present, and
fallback to fflush otherwise?
For what it's worth, on Solaris it's called __fpurge and is declared
in stdio_ext.h

So it seems that using fflush(stdin) is probably the wrong thing
to do altogether for a portable application.
ISO C89 and C99 say that fflush(stdin) yields undefined behavior,
so I'm inclined to agree.
