+       NetBSD's regexp implementation is now part of libnbcompat.
+       Nblex, nbm4, nbpax, nbsed use it and they may crash on
+       non-NetBSD hosts if linked with stale object files produced
+       while they included a non-NetBSD regex.h.
+       In any case, you should "make cleandir" at least these tools
+       before updating your toolchain.
