references the wrong architecture (usually, contains links to the
i386-based appliance, when the x86_64 appliance should be constructed).
This commit changes libguestfs-supermin-helper so that the script is
the same on all architectures. Instead, the library passes the
differences to the script (eg. $host_cpu). Because the i386 and

guestfish: Use xstrtol to parse integers (RHBZ#557655).
Current code uses atoi to parse the generator Int type and
atoll to parse the generator Int64 type. The problem with the
ato* functions is that they don't cope with errors very well,
and they cannot parse numbers that begin with 0.. or 0x..
for octal and hexadecimal respectively.
This replaces the atoi call with a call to Gnulib xstrtol
and the atoll call with a call to Gnulib xstrtoll.
The generated code looks like this for all Int arguments:
{
strtol_error xerr;
long r;
xerr = xstrtol (argv[0], NULL, 0, &r, "");
if (xerr != LONGINT_OK) {
fprintf (stderr,
_("%s: %s: invalid integer parameter (%s returned %d)\n"),
cmd, "memsize", "xstrtol", xerr);

}
/* The Int type in the generator is a signed 31 bit int. */
if (r < (-(2LL<<30)) || r > ((2LL<<30)-1)) {
fprintf (stderr, _("%s: %s: integer out of range\n"), cmd, "memsize");
return -1;
}
/* The check above should ensure this assignment does not overflow. */
memsize = r;
}
and like this for all Int64 arguments (note we don't need the
range check for these):
{
strtol_error xerr;
long long r;
xerr = xstrtoll (argv[1], NULL, 0, &r, "");

value, and this could have caused silent failures, eg. in the case
where there was not enough disk space to store the resulting file,
