This part doesn't look good to me. The line was meant to provide a declaration
if the system's <string.h> doesn't.

  @item
  This function is sometimes not declared in @code{<string.h>} on some 
platforms:
  glibc 2.8, OSF/1 5.1.

We don't care if gcc makes warnings about duplicate declarations during
configure tests. "-Werror" is not supported at configure-time.
