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; }

"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."

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"

would be output as "1m65.000000s".

Last patch have synced form Manuel Nova III xxreadtoken() function,
corrected (C) form dash debian/copyright, removed my small mistake
with IFS_BROKEN (thanks by Herbert), and synced cmdedit.c from
current CVS (removed libc5 support, your email correction, my (C) year
corertion).

- 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.

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.

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.
