AIX-4.3.3.0, tar-1.13.22, compile problem --

[Paul Townsend]

=====
To the *tar* maintainers who probably already know this,

I encountered the problem below when attempting to compile the most
recent release of *tar* (tar-1.13.22) on an RS6000 with AIX-4.3.3.0.

An additional screwup, mostly mine (:@{), was encountered in `configure'.
If you set "CFLAGS=-O[45]", the check for the existence of "-lcposix"
succeeds even though the library doesn't exist.  Apparently, the linker
used when "-O[45]" is set is different from the linker when "-O3" or
lower is set and it has a relaxed view of fatal errors.  In this case,
"strerror" exists in "-lc" also.  Since the linkage is satisfied, the
alternate linker allows the non-existence of "cposix".  A similar
problem happened with the "-ldir" check.

"tar" was configured with the following `ksh' script.

#!/bin/ksh
if [[ -z "${CFLAGS}" ]]; then
  HOSTOS=`uname -s`
  case $HOSTOS in
    AIX)
      CFLAGS="-O3 -qstrict"

The following patch eliminates the above errors.  I don't think it
changes the intent of the original code.
