+Subject: [PATCH 1/3] gfanlib/Makefile.am: use LIBADD for additional libraries.
+
+The $GMP_LIBS and $CDDGMPLDFLAGS variables were being added to
+libgfan_la_LDFLAGS, which isn't quite correct. Since both contain
+library (-l) flags, they belong in _LIBADD rather than _LDFLAGS:
+
+  https://www.gnu.org/software/automake/manual/html_node/Libtool-Flags.html
+
+This commit moves them to a new libgfan_la_LIBADD variable.
