lukem d6c354cb4b * remove CFLAGS+=-w for powerpc (added in 1.26):
- it was in the wrong place
	- makefiles shouldn't override CFLAGS; only CPPFLAGS and COPTS
	- christos fixed unsigned char stuff in 1.33 which should
	  remove the need for -w anyway
* move .include <bsd.prog.mk> to EOF

christos 505573954e Unfortunately (as I expected) the previous change broke:
sleep
    cmd='set `type "sleep"`; eval echo \$$#'
    which=`eval $cmd`
    echo $which

because the region did not get recorded at all, and it was interpreted as
a single word. I modified the code to keep track when the result of a
backquote expansion has been recorded to avoid recording it twice. I still
feel that this is not the right fix... More to come.

prints:

because when the arquments are not quoted, the backquote result
gets recorded twice.  The fix right now is to comment out the
record_region() call in expbackq().  I hope that it does not break
anything else.

christos 5accccd051 Fix problem introduced in yesterday's commit that broke both signed and
unsigned character machines. So that people don't have to reverse engineer
this again:
	mksyntax detects if characters are signed or not and builts a syntax
	table that has a base of 129 for signed characters or 1 for unsigned
	characters. This is so the largest negative signed char [-128] + the
	base == 1. 0 is special and means end of file in both cases. PEOF
	is -1 for the unsigned character case and -129 for the signed
	character case, so that syntax[PEOF + base] == syntax[0] == CEOF
	So PEOF has to be -1, but it is explicitly compared with
	unsigned characters on machines where characters are unsigned.
	The quick fix is to define UPEOF the (unsigned char) version of PEOF
	and use that. A better fix is to always use unsigned characters
	when referencing symbol table entries, but that would require
	extensive changes to the shell. So to summarize

	syntax[0] == CEOF, base + PEOF == 0

		unsigned	signed
	base	1		129
	PEOF	-1		-129

christos beb57fb35d - Add function callback capability when variables are set.
- Add setvarsafe that returns an error instead of longjmp() to the
  error code.

christos cc31700a92 - Add getoptsreset to be used as a callback function when OPTIND is set.
This is used to implement the POSIX behavior when OPTIND=1
- Call setvarsafe instead of setvar. If one ran
	"getopts optstr badvariable"
  where badvariable contained an illegal variable name, there was no way
  to recover, since setvar() would longjmp on the error.

christos 0bc88b2434 getopts fixes:
1. OPTIND value was not computed correctly when the argument was part of the
   option string (i.e. for "l:" "-l 1" was working "-l1" was not). (PR/2505).
2. OPTARG was not being unset in case of errors [in the non POSIX error case].
3. optvar could be set to random values.
4. Option string starting with a : was not treated specially as POSIX
   specifies (if the option string starts with a :, then there is no
   error printed when there are missing option arguments or illegal options,
   and OPTARG and optvar are being set specially).
5. Implemented getopts "opts" optvar [arg]. The optional argument case
   was not implemented.

To do:
- what does Posix say about resetting the getopts state? Bash does it
  by setting OPTIND=0; is that correct? Should we be doing the same thing?
- should we be using getopt(3) for everything internal to the shell? Is that
  feasible because we might need to handle multiple invocations at once.
