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.

now only produce ELF objects. It also makes us closer to stock GCC, and
simplifies the set of changes we still need from stock GCC on every import.

under way to move the remnants of the a.out toolchain to ports. As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL. It has already lasted WAY beyond
that.
Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.
Tested on: i386 (extensively), alpha
cc1plus can apparently be built if you happen to have
/usr/bin/gperf, or set CXX to point to a C++ compiler
that can build gperf(1) in the bootstrap-tools stage
of buildworld.
The problem is the GCC driver now turns STANDARD_EXEC_PREFIX into a relative
path -- "<basename argv[0]>/../../libexec" for our normal install location.
However, in the middle of `buildworld' we need
"<basename argv[0]>/../../../../libexec" due to the prefix we tell the GCC
driver. But either the GCC driver is buggy, or we are confusing it, as it
tries to exec "<basename argv[0]>/../../libexec/cpp0" as if it were installed
in the normal place (but isn't).
MD_EXEC_PREFIX is still absolute, so I'll use that for now. I would like to
later make it so MD_EXEC_PREFIX is set only for `buildworld', as
MD_EXEC_PREFIX is also in the search path for libraries. Don't ask me why!
Another way is to add ${OBJFORMAT_PATH} (as set in CROSSENV) to the PATH
in src/Makefile.inc's WMAKEENV.
