You also need the AC_REPLACE_GNU_GETOPT macro definition... but I
don't know where you might find that -- at the autoconf macro
repository perhaps?

$ ls replace/
...
getopt.c
getopt1.c
gnu-getopt.h
configure.in:
AC_CHECK_FUNCS(getopt_long, [],
[LIBOBJS="$LIBOBJS getopt.$ac_objext getopt1.$objext"
rm -f replace/getopt.h
$LN_S ./gnu-getopt.h replace/getopt.h])
...
Xsed="sed -e s/^X//"
LTLIBOBJS=`echo "$LIBOBJS | \
[$Xsed -e "s,\.[^.]* ,.lo ,g;s,\.[^.]*$,.lo,"]
AC_SUBST(LTLIBOBJS)
replace/Makefile.am:
noinst_HEADERS = gnu-getopt.h
noinst_LTLIBRARIES = libreplace.la
libreplace_la_SOURCES =
libreplace_la_LIBADD = @LTLIBOBJS@
But if you want to understand all the hoops this code jumps through,
you will need to reads the book =)O|
Cheers,
Gary.
