[bug-gnulib] removed fts-lgpl dependency on unistd-safer

[Paul Eggert]

I installed this to remove an inadvertent dependency of fts-lgpl
on unistd-safer.

2005-05-22  Paul Eggert  <address@hidden>

        * fts.c (fd_safer) [_LGPL_PACKAGE]: New static function,
        so that unistd-safer.h (GPL'ed code) need not be included.
