anymore as building -CURRENT sources on 3-STABLE was the reason for the
previous revision adding this.
Note that since the GCC Project moved mkstemp.c from GCC's world to
libiberty, we no longer support building -CURRENT sources on non-FreeBSD
boxes unless that box has a very simular libc mix as FreeBSD.
__FreeBSD_version < 400004.
This allows -STABLE to build -CURRENT sources.
[mkstemps() was added to -current just before the version bump to 400004
(a matter of hours in this case), so the test is as exact as possible.]

When I imported EGCS into contrib/egcs/ I failed to prune out
egcs/gcc/cp/hash.h which is generated from gxx.gperf. Thus `cc1plus' wasn't
using the hash.h we generated by cc/cc_tools/Makefile, but rather the one in
egcs/gcc/cp/.
When I imported contrib/gcc/ I did prune gcc/cp/hash.h. Unfortunately the
GCC maintainers weren't smart on their file nameing and there is also a
egcs/gcc/hash.h (name overloading does NOT work as well on the filesystem
as in C++...). Due to the -I ordering we are were then picking up gcc/hash.h
when compiling `cc1plus'.
Configuration header inclusion has been moved around to reduce diffs from
the offical GCC distribution. We now generate the same ``tm.h'' produced by
gcc's `configure' script [minus all the "#ifdef IN_GCC"'s].
Jeff Law of EGCS/Cygus says the new "approved" way of doing configure-related
includes is to list them all in ``tm.h'' rather than having the architure
config headers include large numbers of other configure headers.

underscore handling is the only thing that differs for aout and

code still applies, but the code attached to it had rotted:
# ../Makefile.inc will put an absolute path to our objdir in CFLAGS.
# Prevent mkdep from using it, so that we don't have to give rules for

Many other makefiles seem to have the same bug (i.e., spelling "." as
"${.OBJDIR}" or as an even more complicated alias in -I directives).
The previous commit made things worse by breaking the -j0 case and
moving around the breakage for the -jN case. The fix involves
restoring .ORDER statements that were deleted in the previous commit,
removing wrong special handling of tree-check.h, and rewriting the
generation of fudged dependencies based on an idea I got from the
previous commit (filter out problematic objects first).

to the depend target. It "works" for the depend target by skipping

the beforedepend targets in the tree a no-op except for this bug.
Removed vestiges of elf and aout targets.
a.out gas and the binutils gas (elf or a.out) with a single compiler.
This uses other infrastructure not yet committed, in order to support
both a.out and elf it needs to be able to get to both a.out and elf
gas, ld, libs, crt* etc. So for now, the support is pretty much dormant.
The new freebsd.h file is based on the old freebsd-elf.h file (which has a
long lineage, right back through linux and svr4 files). The change is
pretty dramatic from a gcc internals standpoint as it overrides a lot of
definitions in order to generate different output based on target mode.
There is potential for screw-ups, so please be on the lookout - gcc's
configuration mechanism wasn't really meant for this kind of thing.
It's believed to compile world etc just fine under both a.out and elf, can
handle global constructors and destructors, handles the differences in
a.out and elf stabs, and what sections things like exceptions go in.
The initial idea came from i386/osfrose.h which is a dual rose/elf format
target. These two are not as diverse as a.out and elf it would seem.
The cc front-end uses external configuration to determine default object
format (still being thrashed out, so read the source if you want to see
it so far), and has a '-aout' and '-elf' override command line switch.
There are some other internal switches that can be accessed, namely -maout,
-mno-aout, -munderscores and -mnounderscores. The underscore and local
symbol prefixing rules are controllable seperately to the output format.
(ie: it's possible to generate a.out without the _ prefixes on symbols and
also to generate elf with the _ prefixes. This isn't quite optimal, but
does seem to work pretty well, except the linkers don't always recognise
the local symbols without their normal names)
The default format is a.out (still), nobody should see any major changes.
With both elf and a.out tools and libraries installed:

GCC-2.6.1 COMES TO FREEBSD-current
----------------------------------
Everybody needs to 'make world'.
Oakland, Nov 2nd 1994. In a surprise move this sunny afternoon, the release-
engineer for the slightly delayed FreeBSD-2.0, Poul-Henning Kamp (28),
decided to pull in the new version 2.6.1 of the GNU C-compiler.
The new version of the compiler was release today at noon, and hardly 9
hours later it was committed into the FreeBSD-current source-repository.
"It's is simply because we have had too much trouble with the version 2.6.0
of the compiler" Poul-Henning told the FreeBSD-Gazette, "we took a gamble
when we decided to use that as our compiler for the 2.0 release, but it
seems to pay of in the end now" he concludes.
The move has not been discussed on the "core" list at all, and will come as
a surprise for most Poul-Hennings peers. "I have only discussed it with
Jordan [J. K. Hubbard, the FreeBSD's resident humourist], and we agreed that
we needed to do it, so ... I did it!". After a breath he added with a grin:
"My email will probably get an all time 'disk-full' now!".
This will bring quite a flag-day to the FreeBSD developers, the patch-file
is almost 1.4 Megabyte, and they will have to run "make world" to get
entirely -current again. "Too bad, but we just had to do this." Was
the only comment from Poul-Henning to these problems.
When asked how this move would impact the 2.0 release-date, Poul-Hennings
face grew dark, he mumbled some very Danish words while he moved his fingers
in strange geometrical patterns. Immediately something ecclipsed the Sun, a
minor tremor shook the buildings, and the temperature fell significantly.
We decided not to pursure the question.

We BADLY need somebody to look at the 'freebsd' OS in gcc, sanitize it and
carry the patches back to the GNU people. In particular, we need to get
out of the "i386-only" spot we are in now. I have the stuff to take a
gnu-dist into bmake-form, and will do that part.
