seems like you created a symbolic link from the -04-04 to the -04-14.
I didn't, but the Warwick webserver has this way of error-correcting URLs.

See also my recent comments at #12751.
OK, I have read them now.

namespaces at all...
I also ran into this with my restrict() functions which had to be renamed.
No, eclib does not yet have its own namespaces. One day.... I already
see that in the code I call my div() functions mostly as ::div() because
of some similar clash, but have not before had a complaint about the
function declaration. I can see the point behind your "bad idea" comment,
but I have been happily using my div(int,int) and div(long,long) functions
for over 20 years, so I got there first!
