d3612178b7 Patch by Junio C Hamano to workaround a gcc compiler bug.
The construct certain vintages of GCC (the one I have trouble
with is 3.2.3) have trouble with looks like the following:

    static struct st a;
    static struct st *p = &a;
    struct st { int foo; };
    static void init(void) { a.foo = 0; }

The problem disappears if we move the struct declaration up to
let the compiler know the shape of the struct before the first
definition uses it, like this:

    struct st { int foo; }; /* this has been moved up */
    static struct st a;
    static struct st *p = &a;
    static void init(void) { a.foo = 0; }

a3822de23e Patch from Bastian Blank to fix a problem when runing find under ash.
"If the shell is compiled with -DJOBS, this is all fine -- find wasn't
stopped (it was killed), so it correctly uses WTERMSIG instead of WSTOPSIG.
However, if the shell _isn't_ compiled with -DJOBS (which it isn't in d-i),
only WSTOPSIG is used, which extracts the high byte instead of the low
byte from the status code.  Since the status code is 13 (SIGPIPE), "st"
suddenly gets the value 0, which is equivalent to SIGEXIT. Thus, ash prints
out "EXIT" on find's exit."

47e5ca1ecb Patch by Jean Wolter to fix a bug where a script wouldnt be executed
unless it had #!/bin/sh in the first line

"It correctly locates the script, tries to execute it via execve which
fails. After that it tries to hand it over to /bin/sh which fails too,
since ash

    - neither provides the absolute pathname to /bin/sh
    - nor tries to lookup the script via PATH if called as "sh script"
"

350d26bbbb - the number of commands in the history list is now configureable via the

 - added a new config option to allow persistant history lists. This is
   currently only used by ash, but the calls ({load,save}_history) could
   be added to the other shells as well.

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.

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(),
and copynode() table implementations.  Commit the fix but keep them disabled
until others check them out.  Uncomment "//#define CMDTXT_TABLE",
"//#define CALCSIZE_TABLE", and "//#define COPYNODE_TABLE" to try them out.
Saves over 600 bytes on i386.
