give the cvs tree a surviving a 'make world'. One of the two diff chunks
is already in gcc-3.3, the other has been committed to gcc's HEAD and
is in the pipeline for gcc-3.3.1 (but has not been committed yet).
The first chunk simplifies an excessively complex assembler statement
when generating switch jump tables. The use of '.' causes as(1) to choke
on big files. Use a simpler form instead. This is only an issue for
TARGET_64BIT mode.
The second chunk fixes an internal compiler error when compiling
libc/stdio/vfprinf.c. While this is supposedly only an issue for
64 bit mode, it does touch the 32 bit i386 code paths, so this patch
is only applied for TARGET_ARCH == amd64 to keep the risks down.
Breaking gcc at the 11th hour would suck.
This will be removed when it is time to import gcc-3.3.

As far as binutils is concerned, the amd64 platform is still called
"x86-64"/"x86_64". Setting things from ${MACHINE_ARCH} breaks that.

FreeBSD. This method attempts to centralize all the necessary hacks
or work arounds in one of two places in the tree (src/Makefile.inc1
and src/tools/build). We build a small compatibility library
(libbuild.a) as well as selectively installing necessary include
files. We then include this directory when building host binaries.
This removes all the past release compatibilty hacks from various
places in the tree. We still build on tip of stable and current. I
will work with those that want to support more, although I anticipate
it will just work.
Many thanks to ru@, obrien@ and jhb@ for providing valuable input at
various stage of implementation, as well as for working together to
positively effect a change for the better.
or dead kernel core is loaded into gdb. This extends gdb's existing
shared library support, so the "info sharedlibrary", "sharedlibrary"
and "nosharedlibrary" commands can be used to view and change the
list of loaded symbol files.
The current implementation is more than a kludge however, and it
will not always manage to find the .ko.debug file corresponding to
the loaded module. In particular, for modules whose build directory
cannot be easily guessed from the module name such as all the
netgraph modules, the debug version of the .ko will not be found
automatically.
The logic for finding the module file first attempts to guess at
the module build directory by parsing the version[] string. Then
using that directory ($DIR), it tries the following paths in turn:
./<module>.ko.debug ./<module>.ko
$DIR/<module>.ko.debug $DIR/<module>.ko
/boot/kernel/<module>.ko.debug /boot/kernel/<module>.ko

options.h to config.h.in and set via ./configure when built normally.
Export some of the build knobs to the Makefile here, overridable
from /etc/make.conf. Also get the version strings right.
config.h was repocopied to config.h.proto, and we do a limited sed on it
at build time now.

make it easier to find how `interactive merging' works with sdiff.
