Sorry to appear dense, but is there a url I need to know, or an ftp 
procedure, or what?  I don't have CVS installed (though I can get it, 
of course), but what do I need to do to get to this anon CVS site and 
get the sources?  Is there a concise doc on this anywhere?  What is the 
address of the site?

OK, I understand now.

So to use these enhanced functions, programmers will use 64-bit values 
in 64-bit structures that parallel the current 32-bit ones, right?  But 
since fcntl uses a vararg plist, they will *not* have to use fcntl64 to 
utilize the new functions, just pass an appropriate command and an 
flock64 structure to the existing fcntl.  And the new flock function 
should also use these new arguments, to support 4GB files?

Please correct me if I have got any of this wrong.
