Yes.

I'm not convinced, because it's code in libtool.m4 that seems to break 
reliably. Perhaps libsnprintfv doesn't exercise this code? Try this... 
Put this line (from _LT_AC_SHELL_INIT) in a configure.ac and see if CVS 
autoconf will process it:

  AC_DIVERT_PUSH(AC_DIVERSION_NOTICE)

When I do this, I see the same error I mentioned above.
