diffutils-2.7 errors.

[Ksenia Golod]

Hi!

I am trying to make the diffutils-2.7, and getting a whole bunch of compile 
errors:
The first one had to do with dir.c (line: register DIR* reading = opendir 
(dir->name);), and this was resolved when I included #include <dirent.h>.
Now I'm getting:
./util.c: In function `begin_output':
./util.c:206: `F_DUPFD' undeclared (first use this function)
./util.c:206: (Each undeclared identifier is reported only once
./util.c:206: for each function it appears in.)

Any help?
Thanks a lot!
