I have back tracked how libtool gets it's entry for archive_expsym_cmds

configure sets it to the value in lt_archive_expsym_cmds.   That value is set 
in
a generic rountines that escapes meta characters for a number of different 
variables.
The orginal variable it uses is without the lt_.
I back tracked in configure where archive_expsym_cmds gets set for AIX to the 
lines below:

          # This is similar to how AIX traditionally builds it's shared 
libraries.
          archive_expsym_cmds="\$CC $shared_flag"' -o $output_objdir/$soname 
$libobjs deplibs $compiler_flags ${wl}-bE:$export_symbols 
${wl}-bnoentry${allow_undefined_flag}~$AR $AR_FLAGS 
$output_objdir/$libname$release.a $output_objdir/$soname'

I then traced back where these lines come from:  configure.in   
AM_PROG_LIBTOOL.
AM_PROG_LIBTOOL is a macro in aclocal.m4 aliased to AC_PROG_LIBTOOL, also in 
aclocal.m4.

AC_PROG_LIBTOOL has the following code:

        # This is similar to how AIX traditionally builds it's shared 
libraries.
        _LT_AC_TAGVAR(archive_expsym_cmds, $1)="\$CC $shared_flag"' -o 
$output_objdir/$soname $libobjs $deplibs $compiler_flags 
${wl}-bE:$export_symbols ${wl}-bnoentry${allow_undefined_flag}~$AR $AR_FLAGS 
$output_objdir/$libname$release.a $output_objdir/$soname'

Making the convenience fix here should resolve the problems on AIX 5.1, and 
half of the problem on AIX 4.3.3.

        # This is similar to how AIX traditionally builds it's shared 
libraries.
        _LT_AC_TAGVAR(archive_expsym_cmds, $1)="\$CC $shared_flag"' -o 
$output_objdir/$soname $libobjs $convenience $deplibs $compiler_flags 
${wl}-bE:$export_symbols ${wl}-bnoentry~$AR $AR_FLAGS 
$output_objdir/$libname$release.a $output_objdir/$soname'

The other half of the fix for AIX 4.3.3 can be done in the Makefile.am files. 
 After making these changes run the autotools to propagate the changes.
