freddy,

I removed all the lines from configure that you had suggested
but the compile still keeps failing at the same location with 
the same errors.

Well... I discovered the problem. Looking at previous mail:

creating libtds_objects.la
(cd .libs && rm -f libtds_objects.la && ln -s ../libtds_objects.la
libtds_objects.la)
        /bin/sh ../../libtool --mode=link cc  -g    -o libtds.la -rpath
/usr/local/lib -version-info 3:0:0  libtds_objec
ts.la  -liconv ../replacements/libreplacements.la
generating symbol list for `libtds.la'
/usr/bin/nm -B -BCpg   ./.libs/libtds_objects.a
../replacements/.libs/libreplacements.a | awk '{ if ((($2 == "T") || ($2
 == "D") || ($2 == "B")) && (substr($3,1,1) != ".")) { print $3 } }' |
sort -u > .libs/libtds.exp
cc -Wl,-bM:SRE -o .libs/libtds.so.3    -liconv -lc
-Wl,-bE:.libs/libtds.exp -Wl,-bnoentry ${wl}-berok
ld: 0711-244 ERROR: No csects or exported symbols have been saved.
make: 1254-004 The error code from the last command is 8.

Now, where this code come. It come from libtool. It seems that libtool
1.5.x it's a little broken with AIX... you should have GNU nm (check
with "nm -V" command). libtool strip all symbols starting with '.'
however Visual C compiler prefix ALL functions with '.' so it strip all
symbols we require...

>From configure you can find code similar (depending from libtool
version) to

    aix4* | aix5*)
      if test "$host_cpu" = ia64; then
        # On IA64, the linker does run time linking by default, so we
don't
        # have to do anything special.
        aix_use_runtimelinking=no
        exp_sym_flag='-Bexport'
        no_entry_flag=""
      else
        # If we're using GNU nm, then we don't want the "-C" option.
        # -C means demangle to AIX nm, but means don't demangle with GNU
nm
        if $NM -V 2>&1 | grep 'GNU' > /dev/null; then
          export_symbols_cmds='$NM -Bpg $libobjs $convenience | awk
'\''{ if (((\$2 == "T") || (\$2 == "D") || (\$2 == "B")) &&
(substr(\$3,1,1) != ".")) { print \$3 } }'\'' | sort -u >
$export_symbols'
        else
          export_symbols_cmds='$NM -BCpg $libobjs $convenience | awk
'\''{ if (((\$2 == "T") || (\$2 == "D") || (\$2 == "B")) &&
(substr(\$3,1,1) != ".")) { print \$3 } }'\'' | sort -u >
$export_symbols'
        fi
        aix_use_runtimelinking=no

Try to remove lines that start with "export_symbols_cmds=" and run again
configure script. I'll write a bug report to libtool.
