# 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.
