The test for the existence of 'wc' fails on at least IRIX and Solaris:

+xc_tst_str='unknown unknown unknown unknown'
+xc_tst_str=`echo "$xc_tst_str" 2>/dev/null \
+ | wc -w 2>/dev/null`
+case "x$xc_tst_str" in @%:@ ((
+ x4)
+ :
+ ;;
+ *)
+ echo "$xc_msg_err 'wc' utility not found in 'PATH'. $xc_msg_abrt" >&2
+ exit 1
+ ;;
+esac

This is because on those architectures 'wc' outputs the number(s) with
leading zeros, consider:

Linux:
$ echo "h h h h"|wc -w
4

IRIX, Solaris:
$ echo "h h h h"|wc -w
             4

So the check for 'x4' will fail as the string is actually 'x 4'

Not certain what would be the least clumsy way of fixing it.. short of
removing the test, as I don't know any *nix variant which doesn't have
a 'wc' in the most basic PATH.
