# XXX - this is *not* finding dladdr() on OS X (at least not on
# Mountain Lion), even though it's available; autoconf does find
# it. The dl* functions can be tricky, in that they might be
# exported by the run-time linker rather than by any library,
# so the only way to check for it that might work is "can I link
# a program that calls this function?", not, for example, "do
# any of these libraries define this function?"
