Four unit tests fail, or all fail except four? I assume you meant the
former. I'm not sure what the failures mean, can you check if they are
really bad or just some numbers a little bit off. I'm guessing these
routines are calling into MKL.

The *.xxx.src files are templates that are processed by
numpy/distutils/conv_template.py to produce *.xxx files. When you have to
repeat basically the same code with umpteen different types a bit of
automation helps. The actual conversion is controlled by the setup/scons
files, I don't remember exactly where.
