Re: O_LARGEFILE missing

Uli> Probably none.  Make it a file which always fail (i.e., use #error).

Here's a patch.  Port maintainers of m68k, sh, ia64, arm and s390:
Please provided a bits/fcntl.h for your architecture!

Andreas

2000-09-01  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/sysv/linux/bits/fcntl.h: Always fail.

	* sysdeps/unix/sysv/linux/powerpc/bits/fcntl.h: New file.
