e9749129ad sh: Detect dividing the smallest integer by -1.
This overflows and on some architectures such as amd64 it generates SIGFPE.
Generate an error on all architectures.

8832864298 In the spirit of r90111, depend on c89 and remove the "STATIC" macro
and its usage.

aa7b6f8259 Consistently use "STATIC" for all functions in order to be able to set
breakpoints with in a debugger.  And use naked "static" for variables.

9d22cd9be8 If DEBUG is 3 or greater, disable STATICization of functions.
Also correct the documented location of the trace file.

39376f45e2 - Fix bugs where the value of arithmetic expansion$((...)) was trucated
to type int.
- Change the type used for arithmetic expansion to intmax_t (ie. 64 bit on all
  currently supported FreeBSD architectures).  SUSv3 requires at least type
  long but allows for larger types.  Other shells (eg. bash, zsh, NetBSD's sh)
  do that too.

d62ec71c31 Rename the trace() function (that is build only in the -DDEBUG=2
case), so that it doesn't clash with the ncurses function of the same
name when linking statically with -ltermcap.

The linker only complains when -static is used, and it is not clear
whether this is a bug.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

958ba632fa Make sh(1) a little braver in the face of adversity. sh(1)
now handles the getpwd() init problem the same way as bash
and ksh do.  Also while I was in here, I cleaned up the format
a little, removed some unnnecessary #if SYMLINKS cruft, and
changed the pwd builtin to use getcwd(3) as Joerg suggested.

8a8c5e4e92 oops, I didn't mean for the unconditional DEBUG code to go in, it's been
off in FreeBSD for some time.  I realised this a few seconds after the
commit started..

aa9caaf657 Merge of 4.4-Lite2 sh source, plus some gcc -Wall cleaning. This is a
merge of parallel duplicate work by Steve Price and myself. :-]

There are some changes to the build that are my fault...  mkinit.c was
trying (poorly) to duplicate some of the work that make(1) is designed to
do.  The Makefile hackery is my fault too, the depend list was incomplete
because of some explicit OBJS+= entries, so mkdep wasn't picking up their
source file #includes.

This closes a pile of /bin/sh PR's, but not all of them..

47a052e00f Make the shell handle a null command in a &&/|| sequence correctly.
The && and || tokens do also terminate a command, not only the
newline.

While i was at it, disabled trace code by default, it served no good
purpose since it required the use of a debugger anyway to be turned
on.  Instead, placed a hint in the Makefile on how to turn it on.

This makes the shell ~ 10 % faster and ~ 4 KB smaller. :)
