Please unmunge the init_module() function names in the back-* modules.  They're
not necessary and force users to use .la files, which cause breakage in other
ways.  The only time the name munging like that is necessary is if you're using
ltdl's dlpreopen for static stuff, which I wouldn't recommend and don't know of
anyone who actually does use that.  I'd be happy to supply a patch if you'd
like, I've already made the change and removed the .la files here and everything
is working fine so far.
