A whole bunch of files are failing to compile with warnings like this:

../../../../kern/tty.c: In function 'ttyoutput':
../../../../kern/tty.c:740: warning: pointer targets in passing argument 1 of 'b_to_q' differ in signedness

This is today (20060710)'s tree and a system built last Friday
(20060707).

I've filed PRs with patches for dev/ic/aic7xxx_osm.c and
dev/scsipi/cd.c, but I think I'm going to stop for now (as I have
other things I need to get done today...)

These are the files that are failing on me (but I'm not building
GENERIC so it's probably not a complete list):

   fs/cd9660/cd9660_lookup.c
   fs/cd9660/cd9660_node.c
   fs/cd9660/cd9660_rrip.c
   fs/cd9660/cd9660_vfsops.c
   fs/cd9660/cd9660_vnops.c
   kern/core_elf32.c
   opencrypto/cryptodev.c
   opencrypto/cryptosoft.c
   dev/dkwedge/dk.c
   ufs/ffs/ffs_vfsops.c
   dev/usb/hid.c
   netinet/if_arp.c
   ufs/mfs/mfs_vfsops.c
   dev/scsipi/scsiconf.c
   dev/scsipi/scsipi_verbose.c
   dev/scsipi/sd.c
   kern/tty.c
   dev/usb/uhidev.c
   arch/i386/pci/viapcib.c
   arch/i386/i386/vm86.c
   dev/vnd.c
   dev/wscons/wsemul_vt100_subr.c

gcc -v gives

   Using built-in specs.
   Target: i386--netbsdelf
   Configured with: /usr/src/tools/gcc/../../gnu/dist/gcc4/configure --enable-long-long --disable-multilib --enable-threads --disable-symvers --build=i386-unknown-netbsdelf3.99.17 --host=i386--netbsdelf --target=i386--netbsdelf
   Thread model: posix
   gcc version 4.1.2 20060628 prerelease (NetBSD nb1 20060628)

and there's nothing pertinent in /etc/mk.conf.

It seems surprising that nobody else would be running into this, but
as far as I can tell I'm not doing anything unusual or obviously
stupid, and the machine was freshly installed on Friday...
