[Bug-tar] Build problems under DEC-VAX-Ultrix

[miim webmaster]

(1)

Under DEC-VAX-Ultrix, the routine "strdup" is not
available and the tar build fails.

Quick and dirty fix:

Inserting the following code into src/tar.c
*appears* (see (2) below) to solve the problem.

>char *strdup (const char *s) {
>
>char *d;
>
>if (s == NULL) return NULL;
>if ((d = malloc (strlen (s) + 1)) == NULL) return
NULL;
>memcpy (d, s, strlen (s) + 1);
>return d;
>}

This is not a complete fix, as I have no idea what
conditionalization of the package is required to
ensure it
is not compiled in under architectures that have the
routine.

This fix is not tested to work, due to the additional
problem below.


(2)

The routine "vsnprintf" is not available under
DEC-VAX-Ultrix
and the tar build fails.

The routine is referenced in (at least)
lib/argp-fmtstream.c

After a quick Google search, I have not been able to
find the
source for this routine and am stuck at this point.



If anyone is interested in chasing this bug, I can
make the
host system available for testing.
