Subject: zsh breaks configure scripts

Apple uses zsh as /bin/sh on Mac OS X.  Unfortunately zsh has a 
`feature' that breaks many autoconf configure scripts.  The scripts 
contain lines like:
if test "`CDPATH=:; cd $srcdir && pwd`" != "`pwd`" && .......

The problem is that the zsh cd command insists on printing the directory!

The offending code is in cd_new_pwd() in Src/builtins.c around line 1047:
    if (unset(PUSHDSILENT) && func != BIN_CD && isset(INTERACTIVE))
         printdirstack();
     else if (doprintdir) {
         fprintdir(pwd, stdout);
         putchar('\n');
     }

I suggest that the fprintdir/putchar be called only in interactive 
shells:
    if (unset(PUSHDSILENT) && func != BIN_CD && isset(INTERACTIVE))
         printdirstack();
     else if (doprintdir && isset(INTERACTIVE)) {
         fprintdir(pwd, stdout);
         putchar('\n');
     }
