Hi, Can someone test this on Windows with 0.7.6?
````
x,k = symbols('x,k')
f = exp(-x*x)
fourier_transform(f,x,k)
````
(and report what Python you use).
Windows is (thankfully) not my main platform but I've been testing some
stuff. I run py.exe (a single-exe-file stand-alone python 2.7.8) which
works great with SymPy 0.7.5. But on SymPy 0.7.6, I get the following,
at least with the Fourier command above. Some other commands in my test
set cause errors too, but haven't narrowed them down yet (due to
combination of an Octave bug and my inability to do much on Windows).
