Fork

Add in wordexp support (mostly stubbed out for now) since the busybox
shell, lash, is about to start using wordexp.

Make alloca work using the compiler builtin
-Erik

Reworked the password stuff to be reentrant. Group stuff is
still needing to be reworked.
-Erik

Add strnlen

Fix a bad assertion test.

Move fork to common/syscalls (with NO_MMU check). Add Makefile to sparc so
make clean works.

Fix unified syscall stuff for changed ?stat. Move fork to syscalls.c wrapped
with a check for NO_MMU of course.

I just grabbed the bits dir from glibc 2.1.3 on a sparc box
to facilitate the sparc porting work being done by Mathew Bosworth.

stat and mknod cleanup, take two. Put all the needed junk into syscalls.c
for clarity.
-Erik

Fix up some long standing iterative symbol usage problem, noticed today by
Michael Shmulevich, which was caused by the grafting in of GNU libc header
files.

Patch from Michael Shmulevich (michaels@jungo.com) -- functions were not
declared type function.

Patch from Jean-Yves Avenard to move the getopt globals to their
own file, since at least on SH, weak variables with initial values
(.data stuff) were not working. Moving these to their own file
seems to be a good way to handle it.

Use LDFLAGS, don't always include -nostdlib...

Fixed vfork on i386. Reduced size of __uClibc_syscall.

Fix a couple of bugs: check mode is legal; open file and check success before
calling vfork.

strtok_r.c was not being compiled in, so fix that.

Stupid buglet fix. Don't trash FILE bufstart if buffer allocation fails.

Added __strtok_r function. Change strtok to a wrapper around __strtok_r and
add a weak alias of __strtok_r for strtok_r since optional. Also reduced
code size.

Fix a buglet regarding floating point output for ?nprintf functions.

This evening I've been investigating why linking with the shared uClibc library
was not working when booting busybox as init, even though it workes when run on
my desktop system. I made boot floppy with just /dev, a few /etc entries,
busybox dynamically linked vs uClibc, and /lib with shared uClibc in it. And
just as several people have reported, it didn't work.

So I ran 'ldd /bin/true' and it showed 'true' is linked with the shared library
loader. But 'ldd ./busybox' showed it was only linked with uClibc. Doh! Of
course it couldn't work!

This patch fixes the gcc wrapper so when we link with the shared uClibc
library, we also always link with the correct shared lib loader. With this
patch in place, I have now sucessfully booted busybox linked vs the shared
uClibc library. And it works great!

stdio mostly rewritten... passes lots of tests now.
printf now supports long double, plus some bug fixes.

For some reason the fancy attribute tags were not working on m68k so
I followed environ example which uses asm and it seemed to fix the problem
nicely.

It should be ok on i386. Could some check it please :-)

g++ compatible math defines.

New crt0.S with all init done in 'C' code.
Added in support for C++ contructor/destructor tables.

Reduced the size of sigsets to the minimal needed. Apart from the size,
it has the added advantage of giving the C++ build of m68k-elf-gcc a clean
bill of health.

Added res_init and res_query

Added /etc/hosts processing (parses everytime like a real one :-)

Added support for multiple nameserver lines, still supports multiple
servers on a on single line.

Added "domain" entry. domain and search are mutually exclusive and
override each other (the last one wins, see the resolver(5) man page).

Added dummy "getnetbyname" that returns fail.

Added "res_init" and "res_query".

Added "psignal" function

Update arm for the new way of entering main. BTW, I can now run things on arm
as a shared library, using the glibc shared lib loader. :-)

I've updated the pic case but havn't tested it yet.

Forgot to increment i
