I just noticed that lseek on mingw returns 0 instead of -1 on pipes.
Which means that gnulib's fflush module thinks the pipe is seekable, and
loses data in the pipe instead of behaving as a no-op as it should in
trying to reposition the pipe's location.  Until someone (perhaps me)
writes an lseek module, I can't use the gnulib fflush module in m4.
However, I'm not sure on mingw how to detect whether an fd is open on a
regular file vs. a pipe.  Any ideas?
