* Make the long-awaited change from $Id$ to $FreeBSD$jkh1997-01-141-1/+1
| | | | | | | | 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.
* Fix my own brokeness for the colon operator, when one of the argumentsjoerg1995-11-181-33/+31

* expr(1) didn't comply to Posix.2 and its own man page: anyjoerg1995-08-041-1/+13
| | | | | | | | comparisions have been made as string comparisions, even in cases where both operands clearly qualified as integers. The fix is to make the parser properly analyzing whether an operand is a valid integer or not.

| | | | | | | | | /usr/src/bin. Note that some patches are still needed in that directory. I (Joerg) finished most of Philippe's cleanup. /bin/sh will still need *allot* of work, however. Submitted by: charnier@lirmm.fr (Philippe Charnier)

* Explicitly include <sys/types.h> before including <regex.h>. This isbde1994-09-051-0/+1
| | | | | apparently required by POSIX. It will be required in practice when the bogus inclusion of <sys/types.h> is removed from <stdio.h>.

* 1003.2 requires that lexical comparisons be done in locale specific manner,jtc1993-08-171-34/+29
| | | | | | | so we have to use strcoll() instead of strcmp(). 1003.2 requires that a null string be returned if a string does not match a \( \) subexpression. Replaced fprintf/exit with calls to err and errx as appropriate.
