I think line 12 is
         if test `expr $$fail + $$xpass + $$error` -eq 0; then \

and line 29 is
             if test $$maybe_colorize = yes && test $$count -gt 0; then \

but that doesn't explain why $$fail and others are suddenly empty on those 
platforms. If wc was missing, we would probably have a louder message.

Maybe it doesn't like the inline comment? No, it is probably unrelated 
indeed.
