Avoid a reference after free (detected by asan) - harmless here, but
easy to fix.

kre 2eafa75298 DEBUG only changes. Convert the TRACE() calls in the remaining files

christos ab28bede4c Prefix "Syntax Error" with the program name, if the command name is not 
available. At least this way we get an idea of what program gives us the
message.

garbled 6ac601d8c4 Add error printing for ENAMETOOLONG. Partially addresses PR bin/13850 . 
The actual bug mentioned in that PR no longer exists, but it does cause:
~~~~~: error 63
Which this fix cleans up.

kleink b3df6303a9 Rename `sigset' locals to avoid symbol shadowing warning. 2003-01-16 09:38:37 +00:00
christos c02b3bbdf4 Fixes from David Laight: 
- ansification
- format of output of jobs command (etc)
- job identiers %+, %- etc
- $? and $(...)
- correct quoting of output of set, export -p and readonly -p
- differentiation between nornal and 'posix special' builtins
- correct behaviour (posix) for errors on builtins and special builtins
- builtin printf and kill
- set -o debug (if compiled with DEBUG)
- cd src obj (as ksh - too useful to do without)
- unset -e name, remove non-readonly variable from export list.
  (so I could unset -e PS1 before running the test shell...)

wiz 0b398b282c __STDC__ is always defined on NetBSD, so remove #ifdef __STDC__ (and 
unnecessary #else cases).
