Subject: bug#9140: [PATCH 2/3] large-inode: New module
Date: Fri, 22 Jul 2011 10:22:37 -0700

Here's another module I'm adding to coreutils.
I plan to change coreutils to use it.
Another possibility, I suppose, would be to fold it into
AC_SYS_LARGEFILE.

Herb, can you please try out the effect of this module by
appending "#define _DARWIN_USE_64_BIT_INODE 1" to lib/config.h
after running 'configure'?  Thanks.

* MODULES.html.sh: Add it.
* modules/large-inode, m4/large-inode.m4: New files.
