Re: gnulib portability issues

Patches for any of these problems would be welcome.
As freadahead seems to be most pressing, it sounds
like that's the best one to work on first.

That sounds like a challenge!  How about using
the following patch?  Does it work for you, if
you define SLOW_BUT_NO_HACKS?  If so, perhaps
we should just make SLOW_BUT_NO_HACKS the default.

diff --git a/lib/freadahead.c b/lib/freadahead.c
