Here is the same output from libtool on Fedora 17: bash ../../libtool-kill-dependency_libs.sh ../../libtool --tag=CC --preserve-dup-deps --mode=link gcc -std=gnu99 -std=gnu99 -g -O2 -o test-futimens test-futimens.o libtests.a ../../gnulib/lib/libgnu.la libtests.a -lrt libtool: link: gcc -std=gnu99 -std=gnu99 -g -O2 -o test-futimens test-futimens.o libtests.a ../../gnulib/lib/.libs/libgnu.a libtests.a -lrt (this is using libtool-kill-dependency_libs.sh, but I'm fairly sure that doesn't make any difference). Notice that the first 'libtests.a' is preserved by this version of libtool. I tried simply copying 'libtool' from Fedora 17 into the RHEL 5 libguestfs repo, but that doesn't appear to fix the problem. Still looking at this.
