* [SIGNAL] Use bsd_signal if it exists and signal does notHerbert Xu2005-10-29
| | | | | | | | klibc has bsd_signal instead of signal. So we will define signal as bsd_signal if 1) signal does not exist. 2) bsd_signal exists.
* [SIGNAL] Removed use of __P from error.hHerbert Xu2005-10-29
| | | | | This is the only instance of __P in the entire source so it makes sense to get rid of it rather than making it work with klibc.
* 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.
* [INPUT] Size optimisations in preadbuffer()Herbert Xu2005-10-26
| | | | | | | Added unlikely markers. Reduced switch coverage. Removed p since we now erase NULs as soon as we see them. Use more to store parselleft.
* [INPUT] Fix NUL skipping in preadbufferHerbert Xu2005-10-01

This hurts if there are a lot of NUL characters, but should be a win in normal situations.
* Added eflag fixes for trap and minusc.herbert2005-09-26
| | | | | | Let evaltree handle traps from cmdloop. Reset evalskip after minusc is executed. Stop executing traps once SKIPEVAL is seen.
