I don't see why this change is needed. This code is inside "#ifndef 
_LIBC" so this change should have no effect for glibc. And the change is 
harmful for Gnulib, since for this file Gnulib relies on including 
libc-config.h instead of plain config.h.

I updated Gnulib to reflect this change; see first attached patch. That 
being said, I don't fully understand it. Wouldn't it be more efficient 
for glibc glob to use glibc's internal dirfd by whatever name you prefer?

Anyway, the only difference between what you proposed for glibc and 
current Gnulib glob is the second attached patch; could you please merge 
that into your proposal? That way, the two glob.c files can be 
identical, which is a good thing.

Thanks for following up on this.
