ok, why not?

IMO it does not hurt to keep the module 'strdup' around, for packages who
need to port to very ancient machines (e.g. GNU tar). Like we do for the modules
  strtol
  strtoul
  memchr
  memcmp
  memcpy
  memmove
  memset
  strcspn
  strpbrk

I'm changing MODULES.html.sh to make it clear which modules are only for
obsolete platforms.

2008-09-21  Bruno Haible  <address@hidden>

        * MODULES.html.sh (Support for obsolete systems lacking ANSI C 89): New
        section.
        (Support for systems lacking ANSI C 89): Move stdlib, exit, strtol,
        strtoul, memchr, memcmp, memcpy, memmove, memset, strcspn, strpbrk to
        the new section.
        (Support for obsolete systems lacking POSIX:2001): New section.
        (String handling <string.h>): Move strdup to the new section.
        Suggested by Simon Josefsson and Paolo Bonzini.
