gnulib broken on systems lacking fchdir

[Matthew Woehlke]

(...which, aside from the infamous NSK/OSS you've all come to hate me 
for :-) reportedly includes OS/2. According to "The Linux Programmer's 
Manual" (i.e. 'man fchdir'), "The fchdir call is compatible with SVr4, 
4.4BSD and X/OPEN". Note the conspicuous absence of "POSIX".)

I also noticed that although there is a HAVE_FCHDIR (properly set in 
config.h), it is not being used.

How needed are the *at functions? Can I rip them out? Can I emulate 
fchdir()? Is there some other way to achieve what fchdir() is being used 
for?

(coreutils folks, this means I'm not even going to bother attempting to 
build 6.x again until this is resolved, since it most likely won't work.)
