+# Possibly, we could link dynamically.  But the ABI stability of
+# the inn libraries is questionable.  On Debian only the .a files
+# are in inn2-dev.  The .so's are in inn2.deb, which isn't depended on
+# by inn2-dev, and which doesn't have a # shlibs file for them.
+# So right now we can't sensibly link dynamically.
+#
+# So we pass -Bstatic.
+#
+# Recall that LIBS is generally *prepended* to.  So we need to
+# temporarily put -Bstatic in LDFLAGS so that it ends up before
+# the actual libraries in the following tests.
