- Solaris lacks paths.h and the various _PATH_* #defines.
Check for them in configure.ac and fall back on the
usual suspects when they are missing.
- Older Solaris lacks isblank(), and versions that have it
use a macro. Check for the declaration in configure.ac
and fall back on a naive version when missing.
- Older Solaris does not support %jd (intmax_t) in format
strings, but it does support the PRIdMAX macro from inttypes.h.
Do a configure check for PRIdMAX and use it in the code.
If it doesn't exist, define it to "lld" when sizeof(long long)
equals sizeof(intmax_t) as this is more likely to work on
older systems. Otherwise, use "jd" and hope for the best.
- Older Solaris lacks stdint.h, but inttypes.h provides the
same types and works on all platforms I've tried dash on,
so just use it instead.
- Older Solaris doesn't like it when vsnprintf() is passed
a NULL buffer (in violation of the POSIX spec, of course).
Pass a 1-byte dummy buffer instead.
- Solaris lacks tempfile and mktemp programs. Fall back on a
"good-enough" custom function in mkbuiltins.

As it stands expandarg may return with a non-NULL ifslastp which
then confuses any subsequent ifsbreakup user that doesn't clear
it directly.
What's worse, if we get interrupted before we hit ifsfree in
expandarg we will leak memory.
This patch fixes this by always calling ifsfree in expandarg
thus ensuring that ifslastp is always NULL on the normal path.
It also adds an ifsfree call to the RESET path to ensure that
memory isn't leaked.

When I try to split fields by tabs, dash doesn't honour multiple tabs
between fields as whitespace (at least that's how I interpret [1],
please correct me if I'm wrong).
#!/bin/sh
# "1\t2\t\t3"
TESTSTRING="1 2 3"
# only "\t"
IFS=" "
echo "$TESTSTRING" | while read p1 p2 p3; do
echo "p1=${p1}, p2=${p2}, p3=${p3}"
done

Previously we always expanded here-documents in a subshell. This is
contrary to the POSIX specification and how other shells behave. What's
more this slows down many expansions due to the extra fork (however, it
must be said that it is possible for it speed up certain expansions by
running it simultaneously with the command on two CPUs).
This patch move the expansion into the current shell environment.
Test case:
unset a
cat <<- EOF > /dev/null
${a=NOT}
EOF
echo ${a}BAD
Old result:
BAD
New result:
NOTBAD

This patch adds assignment operator support in arithmetic expansions. It
also changes the type used to intmax_t.

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

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.
