I am running a -current i386 system where /usr/src/sys/arch/i386 is
checked out from the sommerfeld_i386mp_1 branch.  When rebuilding the
system using build.sh, I got the following error:

   CC=/usr/src/tools/obj/tools.NetBSD-1.5ZA-i386/bin/i386--netbsdelf-gcc /usr/src/tools/obj/tools.NetBSD-1.5ZA-i386/bin/i386--netbsdelf-lint -chapbxzF -w -X 272 -d /destdir/usr/include -D_LIBC -DNLS -DYP -DHESIOD -DLIBC_SCCS -DSYSLIBC_SCCS -D_REENTRANT -I/usr/src/lib/libc/include -DINET6 -D__DBINTERFACE_PRIVATE -I/usr/src/lib/libc/../../libexec/ld.elf_so -I/usr/src/lib/libc/dlfcn -DWITH_RUNE -DRUNEMOD_MAJOR=3 -D_PATH_LOCALEMODULE=\"/usr/lib/runemodule\" -DRESOLVSORT -I. -DPOSIX_MISTAKE -DPORTMAP -DFLOATING_POINT -i LintSysNoerr.c
   /destdir/usr/include/machine/atomic.h(49): warning: conversion from 'unsigned long' may lose accuracy [132]
   *** Error code 1

Is this a bug, or am I doing something wrong?  In any case, I worked
around it with the following change:
