* Update watch file to only track GNOME 2.20 as gtk-engines was then ported to gtk3 and finally abandoned. * Fix FTBFS due to missing -lm. - New patch 20_link-with-libm, adds AC_CHECK_LIBM and AC_SUBST(LIBM) to configure.ac and $(LIBM) to Makefile.am files for engines which need it in LIBADD. - New patch 90_autoreconf, generated with autoreconf -fi %% rm -rf autom4te.cache engines/support/*~; needed for 20_link-with-libm. - Drop patch 99_ltmain_as-needed, doesn't apply anymore since the addition of 90_autoreconf, but is probably obsoleted by it.
