I agree with the reasoning and approach. But
1) The patch is missing documentation changes.
2) I don't see the reasoning for adding the dependency to modules
like 'acl', 'javacomp' and 'same'. If you are adding a dependency to
these modules, it sounds like every piece of application code that
somehow deads with files via <unistd.h> or <sys/stat.h> would need
a dependency to 'largefile'? This is not comforting, because this
"somehow" is impossible to document.
So, the first question is: What C library symbols are affected?
On a glibc system, I get this list:
$ nm /lib/libc.so.6 | grep ' [A-Z] .*64' | awk '{ print $3 }' | sed -e

doc/glibc-functions/versionsort.texi
For not all of them it's documented. I'm applying the doc patch below.
It documents the current state (before any change in module dependencies).
For alphasort, globfree, fts_close, fts_open, fts_set, versionsort, there
is nothing to document because these function don't change their behaviour
through AC_SYS_LARGEFILE.
Among these affected system functions, those that have a gnulib module are:
doc/posix-functions/alphasort.texi alphasort
doc/posix-functions/fopen.texi fopen
doc/posix-functions/freopen.texi freopen
doc/posix-functions/fseek.texi fseek
doc/posix-functions/fseeko.texi fseeko
doc/posix-functions/fstatat.texi openat
doc/posix-functions/ftell.texi ftell
doc/posix-functions/ftello.texi ftello
doc/posix-functions/glob.texi glob
doc/posix-functions/globfree.texi glob
doc/posix-functions/lseek.texi lseek
doc/posix-functions/lstat.texi lstat
doc/posix-functions/mkstemp.texi mkstemp
doc/posix-functions/open.texi open
doc/posix-functions/openat.texi openat
doc/posix-functions/pread.texi pread
doc/posix-functions/pwrite.texi pwrite
doc/posix-functions/scandir.texi scandir
doc/posix-functions/stat.texi stat
doc/posix-functions/tmpfile.texi tmpfile
doc/glibc-functions/mkostemp.texi mkostemp
doc/glibc-functions/mkostemps.texi mkostemps
doc/glibc-functions/mkstemps.texi mkstemps
Would it not be sufficient to add 'largefile' as a dependency of these
modules? Then, for example, the 'javacomp' module would automatically
indirectly depend on 'largefile':
javacomp -> clean-temp -> open -> largefile
And gnulib users would not have to think about large files specially:
they just look in the documentation for modules that correspond to POSIX
functions.
