ftp: links m4-latest point to 1.4.15

[Albert Reiner]

Hi,

I just noticed that the links m4-latest-... in the download directory on 
ftp://ftp.gnu.org/gnu/m4 point to version 1.4.15 rather than 1.4.16:

lrwxrwxrwx    1 3003     3003           17 Aug 31  2010 m4-latest.tar.bz2 -> 
m4-1.4.15.tar.bz2
lrwxrwxrwx    1 3003     3003           21 Aug 31  2010 m4-latest.tar.bz2.sig 
-> m4-1.4.15.tar.bz2.sig
lrwxrwxrwx    1 3003     3003           16 Aug 31  2010 m4-latest.tar.gz -> 
m4-1.4.15.tar.gz
lrwxrwxrwx    1 3003     3003           20 Aug 31  2010 m4-latest.tar.gz.sig ->
m4-1.4.15.tar.gz.sig
lrwxrwxrwx    1 3003     3003           16 Aug 31  2010 m4-latest.tar.xz -> 
m4-1.4.15.tar.xz
lrwxrwxrwx    1 3003     3003           20 Aug 31  2010 m4-latest.tar.xz.sig ->
m4-1.4.15.tar.xz.sig

Please update the links.

Best regards,

Albert.
