Hi, Herbert and friends. I've created a small patch that allows dash
to be built on Mac OS X. I'm contributing it here with the hope that
it's suitable for inclusion in dash.
The changes in this patch are:
- __attribute__((__alias__())) is not supported, add an autoconf check
- open64 is not present although the stat64 family is, separate the
autoconf checks
- A syntax error had slipped into a non-glibc codepath
- mkbuiltins had a nonportable mktemp invocation for the case where
tempfile is not availalble
Nothing in this patch is actually Mac OS X-specific, so it might aid
portability to other platforms as well.

(Herbert: for context, see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=467065 )
This is a real bug in upstream dash, which has existed since at
least dash-0.5.1 (July 2004). It is a latent bug in cmdtxt()
(which I think applies only to pipes) as it handles "if" commands.
The attached patch fixes it for me.
It's possible this patch will fix one or more of #462414,
#462977, and #463649. I'll send messages there to see if
the submitters can test.

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:
<>

There are two kinds of users to copyfd, those that want to copy an fd to
an exact value and those that want to move an fd to a value >= 10. The
former can simply use dup2 directly while the latter share a lot of common
code that now constitutes savefd.

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.

Since nobody has compiled with JOBS turned off for quite a while, it has
bit-rotted. This patch makes it build again.

klibc doesn't have strsignal but it does have sys_siglist.

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.
