I forget what the problem is here.  Couldn't we just define fpos_t to
be 64 bits?

Right.  So, we go with the define in header, export in cygwin.din
method for dealing with that.

Yes, as I was drifting off to sleep last night, I realized that I'd
awake to just this correction from you.  :-)

As long as no one is actually using lacl, I don't see any reason not
to trash it.  Otherwise, keeping an obsolete function around which does
nothing doesn't seem to be too much of a burden.

Maybe the best plan would be to keep the 1.3.* branch around and start
making drastic changes to 1.5.*.  The first checkin could be device
handling, since that is nearly ready.  Then we could add 32/64 bit
support.  Eventually, around 1.5.8 or so, we could make 1.5 the latest
release and trask 1.3.*
