It isn't possible to build the linuxthreads manual because of a double
close bracket in linuxthreads.texi. This patch fixes it and fixes some
markup on the same line. I realise linuxthreads is a very low priority

Please install if OK.
I also need the following attached patch to build linuxthreads against head.
Cheers,
Carlos.
