rTorrent fails to build with clang

rTorrent 0.9.0 fails to build with clang on Mac OS X 10.7:

/Developer/usr/bin/clang++ -DHAVE_CONFIG_H -I. -I../.. -I. -I./.. -I../..  -I/opt/local/include  -pipe -O2 -arch x86_64 -DNDEBUG -I/opt/local/include/sigc++-2.0 -I/opt/local/lib/sigc++-2.0/include   -I/opt/local/include   -I/opt/local/include   -MT window_http_queue.o -MD -MP -MF .deps/window_http_queue.Tpo -c -o window_http_queue.o window_http_queue.cc
window_file_list.cc:126:19: error: variable length array of non-POD element type 'iterator' (aka 'torrent::FileListIterator')

The iterator in this instance should be a POD under C++11, but not C++03. There's a 'c++11' branch of rtorrent you could try, with:

CXX_FLAGS="-Wall -O2 -std=gnu++0x"
or
CXX_FLAGS="-Wall -O2 -std=c++0x"

[rakshasa]

I just merged C++11 compatibility changes to master, if you could try to compile it under gnu++11 (using '-std=gnu++0x') it should/could work.

In any case I'll test it out with clang once it finishes compiling.

[rakshasa]

Everything should compile with clang now.
