This upsets Bruce because the host boostrap build forces tools to be
static anyway. He says I'm abusing NOTOOLS in src/Makefile by using
it to do a aout->elf transition build. One day I'll find a place to
install host tools like these to allow a true cross build.

stderr error. The enclosed patches do 3 things:
(1) Silenced the output to stderr.
(2) Added a -v option to f2c and f77. This will turn on a verbose
mode, and dumps quite a bit of stuff to stderr.
(3) Updated the f2c man page.

`XCC= <relative cc> -B<path to relative cc1> ...'. This is equivalent
when cc and cc1, etc. have just been bootstrapped by `make world'.
The relative versions normally won't work if the target system is
not binary compatible. Bootstrapping different versions of gcc
without going through `make world' is slightly more broken than
before.
Uniformized macro names (P1OBJS -> LIB1POBJS, etc.).
Don't give full paths to sources.
They have been bootstrapped by `make world' since long before the
hacks here were cloned from ../libgcc/Makefile. The versions just
built in "../*" normally won't work if the target system is not binary
compatible.
Don't use OBJS to defeat `make depend'; just put generated sources in
SRCS.
Added temporary files to CLEANFILES.
with `make -jN' because they did the right things to generate cexp.h
without clobbering cexp.c, and there were no missing dependencies on
cexp.h because cexp.h isn't actually used.
Fixed style bugs.
on bi-parser.h. Not having it sometimes (only with `make -j') triggered
a bug suite that led to ordinary cpp output being put in .depend files.
Various bugs (the main one only with `make -j') prevented timely detection
of failure to build and install gnu/usr.bin/cc. Eventually the missing
${WORLDTMP}/usr/libexec/cpp caused ${WORLDTMP}/usr/bin/cpp to be invoked
by cc, and this version of cpp is not suitable for such invocation.
Ordinary cpp output was put in .depend files when cpp terminated options
processing before seeing the -M flag.
Cleaned up.
target. .ORDER doesn't work right, but is used for things related
to the depend target. It "works" for the depend target by skipping
the build of .depend when N >= 2 and there is a non-default
beforedepend target with no rules. Recent fixes made almost all
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:

objects depend on all generated headers doesn't work because it gives
cyclic dependencies. Give enough dependencies explicitly. We no
longer need to use .SINGLESHELL for `make depend'. .SINGLESHELL was
more of a bottleneck than usual because `make depend' makes everything.
Fixed some spelling and English errors.

on the i386, so there are now 4 empty .o files.

This has the objc backend active, and I think I've managed to get the
f77 f2c support through in one piece, but I don't know fortran to test it.
A 'make world' change and libobjc commit will follow.
If you normally do 'make -DNOCLEAN world', do not do so this time, I know
it can fail with groff.
This version of gcc makes a **LOT** more warnings on our kernel.
