zsh 3.1.4 - AIX 4.3.1 build with --enable-dynamic fails

["David R. Favor" <dfavor@xxxxxxxxxxxxxx>]

Here's the command sequence:

   configure --enable-dynamic

      zsh configuration

      Updated `stamp-modobjs'.
      rm -f libzsh-3.1.4.so
      ld -L/usr/local/lib -L/lib   -o libzsh-3.1.4.so  `cat stamp-modobjs`

Doing an *nm -A `cat stamp-modobjs` | egrep start* gives:

   exec.o:   .startparamscope     U          -
   params.o: .startparamscope     T       7156
   params.o: startparamscope      D      22428      12
   params.o: startparamscope      d      21764       4

So there is actually no __start symbol.

Suggestions?
