Sure.

Wow!  You were determined, huh?  Actually if you follow the recipe
I outlined in the last mail, you don't need that macro.  I should have
been clearer that it was an either/or.  Sorry.

Oops.  Careless cut and paste.  You do indeed need that "`" at the end.
I also missed a double quote from tyhe first line, and the X in the
echo command.  Try this instead (I have double checked for correctness
this time):

  Xsed="sed -e s/^X//"
  LTLIBOBJS=`echo X"$LIBOBJS" | \
  [$Xsed -e "s,\.[^.]* ,.lo ,g;s,\.[^.]*$,.lo,"]`
  AC_SUBST(LTLIBOBJS)

It isn't.  You should end up with something along the lines of:

LTLIBOBJS = getopt.lo getopt1.lo

Probably the stuff I misquoted from the book.  If it still doesn;t
work, try it by hand from your shell prompt.  For example, this is
what I get:

  $ echo X"getopt.o getopt1.o" | 
  > sed -e s/^X// -e "s,\.[^.]* ,.lo ,g;s,\.[^.]*$,.lo,"
  getopt.lo getopt1.lo

No worries,
        Gary.
