* [VAR] Remove setvarsafeHerbert Xu2007-10-06
| | | | | The only user of setvarsafe is getopts. However, we can achieve the same result by pre-setting the value of shellparam.optind.
* [BUILTIN] Treat OPTIND=0 in the same way as OPTIND=1Herbert Xu2007-10-06
| | | | | | | | Previously setting OPTIND to 0 would cause subsequent getopts calls to fail. This patch makes dash reset the getopts parameters the same way as OPTIND=1. Both behaviours are allowed by POSIX but other common shells do tolerate this case.
* Copyright/licence updates and remove all traces of sys/cdefs.hHerbert Xu2005-10-29
| | | | | | | | | | | 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.
