A recent round of patches trips up gcc -Werror compilation:

libtool: compile:  gcc -DHAVE_CONFIG_H -I. -DLTDLOPEN=libltdl
"-DLT_CONFIG_H=<config.h>" -DLTDL -I. -I. -Ilibltdl -I./libltdl
- -I./libltdl/libltdl -gdwarf-2 -Wall -Werror -MT
libltdl/libltdl_libltdl_la-ltdl.lo -MD -MP -MF
libltdl/.deps/libltdl_libltdl_la-ltdl.Tpo -c libltdl/ltdl.c  -DDLL_EXPORT
- -DPIC -o libltdl/.libs/libltdl_libltdl_la-ltdl.o
libltdl/ltdl.c:1552: warning: 'advise_dup' defined but not used
make[2]: *** [libltdl/libltdl_libltdl_la-ltdl.lo] Error 1

Applying this as obvious:

2007-07-04  Eric Blake  <address@hidden>

        * libltdl/ltdl.c (advise_dup): Delete function no longer used
        after memleak fix three days ago.
