[src/trunk]: src/usr.bin/make make(1): prepare for WARNS=6
details: https://anonhg.NetBSD.org/src/rev/244e95723399
branches: trunk
changeset: 944985:244e95723399

description:
make(1): prepare for WARNS=6
The FD_* macros from sys/sys/fd_set.h use signed integers on NetBSD 8
and thus produce conversion errors. On NetBSD 9, these macros are fixed
to use 1U instead of 1.
