This patch improves LINENO support by storing line numbers in the parse
tree, for commands as well as for function definitions. It makes LINENO
behaves properly when calling functions, and has the added benefit of
improved line numbers in error messages when the last-parsed command is
not the last-executed one. It removes the earlier LINENO support, and
instead sets LINENO from evaltree when a command is executed

Looks like in contrast to what the dash.1 manual page says, expansion
of PS{1,2,4} does work.
Here is a little patch to set LINENO. The ways in that it is less than
ideal mirror the ways that the line number error reporting is also
less than ideal.
For example if you run this:
(
x=$((1/0))
# Just to add another line
# And another
) # error reports this line
The error reported will be the closing parenthesis even though I
think most people would prefer the error to be the one where x was
set.

This function is no longer used anywhere else.

Actually this (the empty delim) only works with dash by accident.
I've tried bash and pdksh and they both terminate on the first
empty line which is what you would expect rather than EOF. The
real Korn shell does something completely different.
I've fixed this in dash to conform to bash/pdksh.

OK I agree. The reason it was there is because the parser would
have already replaced the dollar sign by an internal representation.
I've fixed it properly with this patch.
Test case:
cat <<- $a
OK
$a
cat <<- ""
OK
echo OK
Old result:
dash: Syntax error: Illegal eof marker for << redirection
OK
echo OK
New result:
OK
OK
OK

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.

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.
