In the old days we were worried about people using gnulib .c files
without using the corresponding .m4 code.  In such a case,
HAVE_DECL_STRNLEN wouldn't be defined, but the code still shouldn't
declare strnlen.

These days the gnulib packaging process pretty much makes these
concerns obsolete.  So it's OK to use "#if !HAVE_DECL_STRNLEN"
nowadays, I think.
