This patch gets rid of the stack mark tracking hack by allocating a little
bit of stack memory if we're at risk of planting a stack mark which may be
grown later. To do this a new function pushstackmark is added which lets
the user pick a bigger amount to allocate since some users do that anyway
after setting a stack mark.

dash-0.5.3 has an issue reading some line lengths [1].
This is reproducable on amd64, but not on other arches for some reason.
$ cat bug.sh
(read line; echo "${line%%=*}") <<EOF
TITLE=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx+xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
EOF
printf "\
TITLE=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx+xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
" | (read line; echo "${line%%=*}")
$ bash bug.sh
TITLE
TITLE
$ dash bug.sh
TITLE=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx+xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
TITLE
Attahced is a patch to fix the issue
Thanks

Because the parser does not recursively parse parameter expansion with respect
to quotes, we can't accurately determine quote status at parse time. This
patch works around this by moving the quote detection to run-time where we
do interpret it recursively.
Test case:
foo=\\
echo "<${foo#[\\]}>"
Old result:
<\>
New result:
<>

Previously code was added so that tilde expansion was carried out
parameter expansions within double quotes. This change was made
with reference the behaviour of bash at the time. Bash has since
be fixed so that this behaviour no longer occurs which is in line
with most other POSIX shells.
So this patch removes that behaviour in dash as well.
Test case:
unset a
echo "${a:-~root}"
Old result:
/root
New result:
~root

Previously tilde expansion was not carried out for =?#% expansion words.
This is contrary to the POSIX specification.
Test case:
a=~root:~root
echo ${a#~root}
Old result:
/root:/root
New result:
:/root

Test case:
a=/b/c/*
b=\\
echo ${a%$b*}
Old result:
/b/c/*
New result:
/b/c/

The return value of ccmatch was being treated as 0 or 1 but
it's actually zero or non-zero. This broke inverted character
class matching.

The existing scheme of using the native char for syntax array indicies
makes cross-compiling difficult. Therefore it makes sense to choose
one specific sign for everyone.
Since signed chars are native to most platforms and i386, it makes more
sense to use that if we are to choose one type for everyone.

All users of mempcpy must include system.h.

Removed obsolete extern declaration on funcnest. This conflits with the
correct static definition.
Changed memtodest prototype to use char * instead of unsigned char *.
Perform the unsigned char cast inside memtodest instead.

klibc doesn't have and doesn't need getpwnam. This change creates
getpwhome which always returns NULL if getpwnam doesn't exist.

This change updates the BSD licence to the three-clause version since
NetBSD has already done so. This makes dash GPL-compatible.
It also adds Christos Zoulas (NetBSD ash maintainer) to the COPYING file.
I've added "copyright by Herbert Xu" to most files.
Finally all CVS IDs and inclusion of sys/cdefs.h have been removed.
The latter is needed for support of klibc.
