Hi Lothar!

This seems strange, there is an implementation of strnlen shipped with
GNU SASL for platforms that doesn't have it.  It is in lib/gl/strnlen.c.
Could you tell if it was built on your platform?  I.e., if there is a
file lib/gl/strnlen.o.  Otherwise, grep for strnlen in ./configure
output to see if the strnlen detection code maybe failed.
