* Fix FTBFS -- missing -lm in build. - New patch, 10_link-with-libm, changes similar to upstream 06eecd20a0c6e27f91265c20fe0ad2f773a51494 "build: link against libm" to call AC_CHECK_LIBM and AB_SUBST(LIBM) in configure.in and use $(LIBM) in libgnome-desktop/Makefile.am. - New patch, 90_autoreconf, result of autoreconf -fi && rm -rf autom4te.cache *~; needed for 10_link-with-libm. - Drop 99_ltmain_as-needed; doesn't apply anymore with 90_autoreconf which likely supersedes it. * Update watch file to only consider GNOME 2.32; gnome-desktop3 source is where latest releases are packaged.
