Subject: Port to GNU/kFreeBSD - FreeBSD kernel + GNU libc,
X-Git-Tag: v0.1~7919
X-Git-Url: http://erislabs.org.uk/gitweb/?a=commitdiff_plain;h=fecc3363511ec92cdb862a17d1c62413cb2a04af;p=gnulib.git

Port to GNU/kFreeBSD - FreeBSD kernel + GNU libc,

which has no openat syscall, yet <fcntl.h> does define AT_FDCWD.
* lib/getcwd.c: Undef AT_FDCWD if there is no openat function.
* modules/getcwd (Depends-on): Add openat.
Reported by Petr Salinger.
