Or we could use a #define switch to move to openat_die at compilation...

It will be better and safer, and will avoid code duplication. BTW for
fts what is I suppose mainly using by -R switch in coreutils we could
use the chdir version ....
(if you do not specifiy FTS_NOCHDIR)

BTW do you agree with merging my fist two patch?
