A NULL pointer for interp->result or an empty string?

I don't expect a bug here. For me, it looks like if there is something
broken with dynamic loading on AIX. A simple way to prove this would
be to take tkiInit.c and to uncomment everything in TkiInit() that is
not a call to Tk_CreateItemType() or Tk_DefineBitmap(). This will
result in a dynamic loadable module which only registers two new
canvas item types and creates a couple of bitmaps. Start wish4.1, load
the module and type "pack [button .b -bitmap icon]". If you get the
same error message, contact the person who wrote the dynamic loading
code for AIX. If it works (you get a button with the Tkined icon), we
have to look somewhere else.
Thomas> Besides, the fix should go in tkined and not Tk.
Perhaps the fix should go in AIX? :-) Compare the tclLoadAix.c module
with tclLoad*.c modules used by other systems and you will understand
why I expect that this error is indeed AIX specific.
