FreeBSD port (28): futimes, lutimes

- Subject: FreeBSD port (28): futimes, lutimes
Hi,
FreeBSD has two system calls futimes() and lutimes(), which are to utimes()
what fstat() and lstat() are to stat(). It seems they can be useful to user
programs (for example, tar and the fileutils could use lutimes()).
The right place to declare them in the headers in <sys/time.h>. So here is
a patch to declare them there.
2002-07-06 Bruno Haible <bruno@clisp.org>
* time/sys/time.h (futimes, lutimes): New declarations.
* sysdeps/generic/futimes.c: New file.
* sysdeps/generic/lutimes.c: New file.
* misc/Makefile (routines): Add futimes, lutimes.
