Right. I appear to have been distracted by the fact that one of the
three cases uses $pwd (which will be set to "/bin/pwd"); however, the
other two just use "pwd" which will be the shell's built-in:

	AC_PATH_PROG(pwd, pwd, pwd)
	
	AC_MSG_CHECKING(for source directory)
	
	if test -z "$srcdir" ; then
	  SRCDIR=`pwd`
	else
	  SRCDIR=`(cd "$srcdir" ; $pwd)`
	fi
	
	AC_MSG_RESULT("$SRCDIR")
	
	AC_MSG_CHECKING(for build directory)
	
	DSTDIR=`pwd`
	
	AC_MSG_RESULT("$DSTDIR")

For the $SRCDIR = $DSTDIR check to work correctly, we need to use $pwd
in all three cases. I'll fix this.
