compiling rtorrent - patching gcc 4.3

Hi! I am trying to have a DHT capable torrent ncurses client.

rtorrent seems right ...

apt-get from the testing branch as described here
only installed an older version without dht :-(
(and I had to add a apt.conf as described here)

So, I followed the instructions on
http://www.howtoforge.com/compile-rtorrent-from-svn-ubuntu-8.04-hardy-heron

and here is where I got stuck

9. Configure it
error missing openssl... fixed it, I had to add
apt-get install libcurl3-openssl-dev

10. Compile libtorrent

make FAILS! Here is what it says:

g++ .... -c file_list_iterator.cc -fPIC -DPIC -o .libs/file_list_iterator.o
In file included from file_list_iterator.cc:42:
file_list_iterator.h: In member function 'uint32_t torrent::FileListIterator::depth() const':
file_list_iterator.h:64: error: 'abs' is not a member of 'std'
make[3]: *** [file_list_iterator.lo] Error 1

Found this hint ("you need to apply a patch"): http://bbs.archlinux.org/viewtopic.php?id=50562

I have gcc version 4.3.1 (Debian 4.3.1-2)

is this the correct patch?
http://www.mail-archive.com/[email protected]/msg00171.html

and what are the commands to apply a patch?

 

Nobody has a hint who I might be able to ask?

Nobody care to speculate or explain the PATCH process?

 

I think I'd try to install another GCC version and then try the compilation again.
