   If you don't have it in your header files, then you
probably don't have it.  A newer ("HP C V7.3-009 on OpenVMS
Alpha V8.3") header file says:

[...]
/*
**  X/Open extended
*/
#if defined _XOPEN_SOURCE_EXTENDED || !defined _ANSI_C_SOURCE

#   if __INITIAL_POINTER_SIZE == 32
#   pragma __pointer_size 32
#   endif

#   if __CRTL_VER >= 70000000
    char *strdup(__const_char_ptr64);
#   endif

#   if __CRTL_VER >= 70301000
    char *strtok_r(char *__s, __const_char_ptr64 __sep, char **lasts);
#   endif
#endif
[...]

   I know nothing, and my patch access is not what it once
was, but I'd guess that you'd need VMS V7.3-1 to get that
"__CRTL_VER >= 70301000", and, unless there's some magic CRTL
patch, that looks unlikely on VAX.  Some cURL code I found
lying around ("...curl-7_21_1.packages.vms]config-vms.h")
says:

[...]
/* Define if you have the `strtok_r' function.  */
/* Condition lifted from <string.h>             */
#if __CRTL_VER >= 70301000
#  define HAVE_STRTOK_R 1
#endif
[...]

And cURL supplies its own lib/strtok.c which includes a
strtok_r().  For Wget, I just said that it's always missing,
and used the GNU lib/strtok_r.c which came in the kit.
