  Greetings!
  
  I came across a broken link on page
  http://gmplib.org/manual/Formatted-Output-Functions.html#Formatted-Output-Functions
  At the bottom of this page is a link to Obstacks
  http://gmplib.org/libc/Obstacks.html#Obstacks but this page cannot be
  found.

Yes, there are several such broken links.  Unfortunately, how this is
meant to work in texinfo.  Does anybody on this list know?
