Don't use tempfile, as it currently runs tempnam(), which is insecure
and fails under pseudo(1).

Ensure dash can build in a default Solaris 9 or older environment:
- Execute scripts with $SHELL rather than /bin/sh, the latter does not
support e.g. "if ! .." used by mkbuiltins.
- /bin/awk does not support ?: syntax, use explicit statements instead.
- /bin/nl requires no spaces between options and arguments.

In mkbuiltins LC_COLLATE is set, but since "The value of the LC_ALL
environment variable has precedence over any of the other environment
variables starting with LC_"
(http://pubs.opengroup.org/onlinepubs/7908799/xbd/envvar.html), this
has no effect when LC_ALL is set.
This breaks when having e.g. LC_ALL=en_US.UTF-8 during make, which
causes the test case
dash -c :
to fail, probably due to broken ordering in builtins.c. The patch
corrects that by clearing LC_ALL.

Encontered this on ancient gcc-2.95.3 environment;
src/builtins.def.in -> src/builtins.def generation emitted
^ $
lines (likely by /* */), which where NOT ignored by
src/mkbuiltins and generating bogus builtins.c.

- 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.

- AIX lacks a WCOREDUMP macro. It's just used to
append "(core dumped)" to the crash message, so
#ifdef around it.
- For some reason, the nl program on AIX defaults
to not printing line numbers ("-b n"), even though
the spec says it should default to "-b t".
Explicitly pass "-b a" for good measure in mkbuiltins.

while merging upstream dash in klibc,
noticed that klibc dash had grown that useful feature.

I've changed it to use LC_COLLATE.

This patch fixes the case where the eval command is used with
set -e and as part of a construct that should not cause the
shell to abort, e.g., as part of the condition of an if statement.
This is achieved by propagating the EV_TESTED flag into the
evalstring function through evalcmd. As this alters the prototype
of evalcmd it is now invoked explicitly by evalbltin. The built-in
infrastructure has been changed to accomodate this special case.
In order to ensure that the EXIT trap is properly executed this
patch clears evalskip in exitshell. This wasn't needed before
because of the broken way evalstring worked where it always clears
evalskip when called by minusc.

Hi, I propose to apply the following patch for dash. The problem is
alloca.h is absent on many platforms including NetBSD I'm running.
Also, NetBSD's version of mktemp doesn't work without temporary
filename pattern.

I've changed this patch so that we just set LC_COLLATE for the sort
command.

tempfile(1) is Debian-specific so let's use mktemp(1) as a fallback.

For systems without getrlimit (e.g., klibc) we will disable ulimit.
In order to achieve this, builtins.def is now produced by cpp which
allows us to use macros such as HAVE_GETRLIMIT in it.
Thie also means that we can get rid of the cflags parsing code in
mkbuiltins.

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.
