Making rsync compile under Mac OS X 10.3.9 with extended attributes

[Vitorio Machado]

Well, it seems that we just use definitions from the system acl.h
So putting the acl.h attached into /Developer/SDKs/MacOSX10.3.9.sdk/ 
usr/include/sys/ should correct first errors.
I'm still studying the code to see if it needs other changes.
