I finally got the time to get the additional info for you (which was not
exactly easy as it happened on a builder system):
$ gcc --version
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-11)
Copyright (C) 2015 Free Software Foundation, Inc.

$ arch
s390
However, the host kernel is 2.6.32-573.22.1.el6.s390x. The build is done
on an s390x RHEL-6 host, but in a mocked s390 RHEL-7 environment :-)

# 1199 "util/virconf.c"
int virConfGetValueSizeT(virConfPtr conf,
const char *setting,
size_t *value)
{
virConfValuePtr cval = virConfGetValue(conf, setting);
virLogMessage(&virLogSelf, VIR_LOG_DEBUG, "util/virconf.c", 1206,
__func__, ((void *)0), "Get value size_t %p %d", cval,
cval ? cval->type : VIR_CONF_NONE);
if (!cval)
return 0;
if (cval->type != VIR_CONF_ULLONG) {
virReportErrorHelper(VIR_FROM_CONF, VIR_ERR_INTERNAL_ERROR,
"util/virconf.c"
# 1212 "util/virconf.c"
, __FUNCTION__,
1214
# 1212 "util/virconf.c"
, dcgettext ("libvirt", "%s: expected an unsigned integer for
'%s' parameter", 5), conf->filename, setting)
;
return -1;
}
if (((unsigned long long)cval->l) > (4294967295U)) {
virReportErrorHelper(VIR_FROM_CONF, VIR_ERR_INTERNAL_ERROR,
"util/virconf.c"
# 1220 "util/virconf.c"

1222
# 1220 "util/virconf.c"
, dcgettext ("libvirt", "%s: value for '%s' parameter must be
in range 0:%zu", 5), conf->filename, setting,
(4294967295U))
;
return -1;
}
*value = (size_t)cval->l;
return 1;
}
Which means SIZE_MAX is 4294967295U.
