+Subject: [PATCH 05/12] fortran/Makefile.am: fix underlinking of libqdmod and
+ libqd_f_main.
+
+The libqdmod library needs to be linked to the just-built libqd, and
+then libqd_f_main needs to be linked to both the just-built libqd and
+the just-built libqdmod. Moreover, both of them need to be linked
+against whatever is in $FCLIBS.
+
+This commit adds two "_LIBADD" lines to fortran/Makefile.am to ensure
+that this happens. Their absence most likely only causes problems when
+the user has "--as-needed" in his LDFLAGS.
