System: NetBSD basalt 1.1A NetBSD 1.1A (BASALT) #124: Thu Feb 22 07:27:34 PST 1996 thorpej@basalt:/work/netbsd/src/sys/arch/hp300/compile/BASALT hp300


>Description:
	The recent "pwd" changes made to /bin/sh changed semantics such
	that the test on line 29 of bsd.obj.mk is always false (i.e
	$here is always the same as $subdir).  This breaks the use
	of /usr/obj.${MACHINE}.

>How-To-Repeat:
	Running csh, do the following:

% ls -l /usr/src
0 lrwxr-xr-x  1 root  wheel  22 Aug  5  1995 /usr/src@ -> /work/netbsd/src
% setenv BSDSRCDIR `cd /usr/src; pwd`
% cd /usr/src/bin/cat
% make obj
making /usr/src/bin/cat/obj.hp300

	Note that previous behavior was:

% make obj
/work/netbsd/src/bin/cat -> /usr/obj.hp300/bin/cat

>Fix:
	Included here is a work around for bsd.obj.mk.  It changes the
	call to "pwd" to "/bin/pwd".  Arguably, /bin/sh should use
	getcwd() rather than translating the path itself.
