many thanks for this! I have wanted to try out the profiler but failed 
to build it (changeset 6 0de294aa75bf):

$ python setup.py install --root=/home/share/software/
running install
running build
running build_py
creating build
creating build/lib.linux-i686-2.4
copying line_profiler.py -> build/lib.linux-i686-2.4
running build_ext
cythoning _line_profiler.pyx to _line_profiler.c
building '_line_profiler' extension
creating build/temp.linux-i686-2.4
i486-pc-linux-gnu-gcc -pthread -fno-strict-aliasing -DNDEBUG -fPIC 
-I/usr/include/python2.4 -c -I/usr/include/python2.4 -c _line_profiler.c 
-o build/temp.linux-i686-2.4/_line_profiler.o
_line_profiler.c:1614: error: 'T_LONGLONG' undeclared here (not in a 
function)
error: command 'i486-pc-linux-gnu-gcc' failed with exit status 1

I have cython-0.9.8.1 and GCC 4.1.2, 32-bit machine.
