Some farther info:
- mntent.h from AIX 4.3.3 included
- i sought some useful strings as arg. for setmntent()
through /usr/inlude/, but was unsuccessful.
- i try pass, as arg 1 of setmntent() NULL, but result is
[zito@p16 fileutils-4.1]$ ./src/df
./src/df: cannot read table of mounted filesystems
- i sought on http://www.rs6000.ibm.com/cgi-bin/ds_form,
but functions from mntent.h are not documented here.
- i try disassemble function setmntent() using gdb
(i am not expert), i found that arg is compared with strings
"/etc/filesystems" or "/etc/fstab". When string
match neither, function returns.
File /etc/filesystems really exists, but /etc/fstab not.
When i try to pass these strings to function setmntent(),
then ./src/df returns information accordingly
to /etc/filesystems definitions.
[zito@p16 fileutils-4.1]$ ./src/df

- old binaries of fileutils-4.0, compiled on AIX4.2.1 returns
following:

I deduce, that functions from /usr/include/mntent.h on AIX 4.3.3
are not implemented for tracking information on mounted filesystems,
or information "mount/not mounted" must be found in some way.
I think configure should found /usr/include/sys/mntctl.h
and /usr/include/sys/vmount.h (like on AIX4.2.1)
and ignore new /usr/include/mntent.h in AIX4.3.3.
Maybe searching in reverse order - first vmount
and after that mntent or something else ...
When I manually correct values in config.h, fileutils-4.1 succesfuly
compiled.
