RE: LFS support on AIX 4.3.3

[Willeat, Todd]

I agree that it would be better to fix the autoconf rather than risk
breaking things on other OSes.

I have recompiled a few more times with the -D_LARGE_FILES option and I
think everything is working correctly now. The dry run gave no errors and so
far the transfer is working fine. My compiler did produce an informational
message about increasing MAXMEM to a value greater than 2048, but if my
current transfer finishes OK, I'm not going to mess with it...

 I committed this to rsync.h (v1.98), so it should be in 2.4.7.  It's
 unconditionally defined.  If somebody on AIX could build from anoncvs
 and confirm that it works that would be great.  (Mail me if you would
 like help with CVS.)

ICK! Please undo your change. Defining _LARGE_FILES as is done in
rsync.h means everyone will be impacted (Solaris, HP-UX, IRIX, Linux,
FreeBSD, Tru64 UNIX, ...). Discussion has already occurred on this
list about LFS support:
  http://lists.samba.org/pipermail/rsync/2000-May/002182.html
  http://lists.samba.org/pipermail/rsync/2000-May/002199.html

If the current configure test is broken for AIX, the autoconf test
should be fixed. Also, Andrew is probably going to move away from the
explicit use of 64-bit data types (like off64_t). Paul Eggert has
written an autoconf macro, AC_SYS_LARGEFILE, which is now a *standard*
part of autoconf in CVS, that detects what to add to CFLAGS and
LDFLAGS to get LFS support on your OS. I think this is the direction
we should head.

LFS support on AIX 4.3.3

[Willeat, Todd]

I've installed rsync 2.4.6 on 2 DEC Alphas and 1 IBM RS/6000. I need to
transfer some files that are  2.5GB. Everything works find between the
DECs, but not with the IBM. On the IBM, I have a problem with files over
2GB. I have successfully concatenated several files into 1 file approx
2.5GB, so there should be not filesystem or ulimit problems. I used IBM C
for AIX, V5 to compile it. Can anyone tell me how to compile rsync to handle
files over 2GB on the IBM?
