Hi! I've been trying to compile zsh 3.1.1 for NeXTSTEP 3.3 and/or OPENSTEP  
4.1. Everything compiles cleanly except for two lines which call the function  
fchdir. NeXTSTEP/OPENSTEP do not implement the fchdir system call so I've  
tried to replace all (all of two) occurances of fchdir(fd) with  
chdir(dirname). Bear with me, I'm only a sys admin not a programmer. Here is  
what I have:

This comes from the Src/compat.c file in the function zchdir(). The variable  
currdir seems to only be assigned file descriptors for the directory "." so  
I replaced fchdir(currdir) with chdir("."). Will this work?

/*    if (currdir == -1 || (currdir >= 0 && fchdir(currdir))) { */
/* Changed by Leo to remove the fchdir function call. */

    if (currdir == -1 || (currdir >= 0 && chdir("."))) {

This comes from the Src/utils.c file in the function lchdir(). The struct d  
seems to always have d->dirname defined (or defined as NULL) so I've replaced  
fchdir(d->dirfd) with chdir(d->dirname). Since both chdir and fchdir have  
the same exit values for the same reasons I assumed the logic wouldn't break.

/*      if (!fchdir(d->dirfd)) { */
/* Changed by Leo to remove the fchdir function call. */

        if (!chdir(d->dirname)) {

If you could help me out I'd really appreciate it. I'm a loyal follower of  
zsh releases but this is the first time I've had to compile it. Obviously, if  
the changes I made are correct and you'd like to add these changes to the  
source code, feel more than free to do so. [my changes do build a working  
executable as far as I can tell.]

I was also told to mention that I'm not a subscriber to the zsh-workers list  
and the output of reporter follows my signature. I can't give you a zsh -f  
report as I can't compile zsh without the changes I made.

Thanks a bundle!

Reporter breaks with the following output if I use my newly compiled zsh  
(3.1.1) or version 2.6 beta 10:
