setfacl(2.4.0): colon missing after x (opts string)?

Sat Dec 19 13:03:00 GMT 2015

Hi Corinna,
setfacl(2.4.0) does not accept -x <acl_entry> (-d <acl_entry> is 
accepted).
Looking at the source of setfacl.c, I believe a colon is missing after x 
in
the opts string (const char *opts).
Regards,
Henri
newlib-cygwin-2.4.0/gnewlib-cygwin-2.4.0/newlib-cygwin/winsup/utils/setfacl.c
shows:
struct option longopts[] = {
 {"remove-all", no_argument, NULL, 'b'},
 {"delete", required_argument, NULL, 'x'},
 {"file", required_argument, NULL, 'f'},
 {"remove-default", no_argument, NULL, 'k'},
 {"modify", required_argument, NULL, 'm'},
 {"no-mask", required_argument, NULL, 'n'},
 {"mask", required_argument, NULL, '\n'},
 {"replace", no_argument, NULL, 'r'},
 {"substitute", required_argument, NULL, 's'},
 {"help", no_argument, NULL, 'h'},
 {"version", no_argument, NULL, 'V'},
 {0, no_argument, NULL, 0}
};
const char *opts = "bd:f:hkm:nrs:Vx"; <==== colon missing after x ?????
static void
print_version ()
