Follow-up Comment #3, bug #34608 (project make):

Hm.  This change is not identical to the original.  To get that you'd need to
write !((t) -1 >= 0) and if you do that then GCC warns again.

However I'm not aware offhand of any numeric implementations where casting a
-1 to an unsigned value yields 0 so maybe this change would be sufficient.
