b230159958 Fixed a timing bug which occured when bb ash is run in a rxvt on the 
HP iPAQ. Sometimes we get a SIGWINCH and want to print the prompt, although
the prompt is not yet initialised (0) .. so just don't print a prompt
as long as the prompt string is 0

d378c3149c Applied vodz' patches #49 and #50 (with a small correction in runshell.c) 
#49: I found one memory overflow and memory leak in "ln" applet.
Last patch reduced also 54 bytes. ;)

#50: I found bug in loginutils/Makefile.in.
New patch have also new function to libbb and
aplied this to applets and other cosmetic changes.

8e139871fe Patch from Stewart Brodie <stewart.brodie@pace.co.uk> to fix ash: 
When alias support is not configured, ash believes that command parameters
that look like dd's "if=/dev/zero" are requests to set a temporary
environment variable whilst dd is running, even though it appears after the
command name.  This is caused by the re-use of the checkalias global variable
to indicate when both alias checking and environment variable checking.  The
failure to reset this flag is due to the reset action being performed only
inside the feature check CHECK_ASH_ALIAS.  Hence ash works as expected when
aliases are configured in, and fails when not.

Example script using 'date' with different settings of TZ:

# TZ=Europe/London
# export TZ
# date
Thu May 30 17:18:49 BST 2002
# TZ=America/New_York date
Thu May 30 12:19:10 EDT 2002
# date
Thu May 30 17:19:12 BST 2002
# date TZ=America/New_York
Thu May 30 12:19:30 EDT 2002    <----- wrong, should be BST time (or error!)
# date
Thu May 30 17:19:35 BST 2002

Attached is a patch against revision 1.52 of ash.c which moves the checks so
that checkalias is updated regardless of whether CONFIG_ASH_ALIAS is set.
With this patch applied, the command shown above which should generate an
error does generate an error.

I have tested this patch with the 'dd' command too and that now works
correctly.

85208e2ab9 Completely rework the config system so that it no longer annoys me to work on 
the busybox development tree.  This eliminates the use of recursive make, and
once again allows us to run 'make' in a subdirectory with the expected result.
And things are now much faster too.  Greatly improved IMHO...

ec07469a3e Patch from Aaron Lehmann <aaronl@vitelus.com>; 
This diff does 2 things:

    1) removes an unnecessary function. saves 64 bytes on i386

    2) allows you to disable checking of mail (actually, it's now disabled
    by default). this would be a nice CML1 option, but for now it's a
    #(define|undef) in the C file like the other internal ash options.
    this saves an additional 352 bytes if you leave mail disabled.

c639a35f50 I stupidly forgot one level of pointer indirection in the cmdtxt(), calcsize(),

until others check them out.  Uncomment "//#define CMDTXT_TABLE",
"//#define CALCSIZE_TABLE", and "//#define COPYNODE_TABLE" to try them out.

ff9eee475f This is a busybox port of the Minix shell. It is reasonably capable, 
handles all the basic stuff (for, case/esac, while, if/then/else), and
is very small (adds just 38k on x86).  It is not as rigorously correct
about Bourne semantics as bash, but for most things it is quite
workable.  There is still some work to be done to further shrink it (it
has its own globbing functions instead of using the libc ones, for
example), but it is quite usable as is.
