The setup() function isn't meant to be called like that, if I understand
correctly what you are doing. It needs command-line arguments in sys.argv. While
the interactive mode stuff is novel to numpy.distutils, the need for
command-line arguments is a restriction in distutil's design. distutils is not
really programmatically drivable. I recommend writing a real setup.py script and
drive it by calling it as a subprocess.
If I don't correctly understand what is going on, please describe it more.
Preferably with code and exactly what you type at the command line to run that code.

Use --fcompiler=g95 as arguments to the build_ext command (and build_clib if you
are building FORTRAN libraries using distutils).

As it's part of numpy, not scipy, no there was no change between scipy 0.5.1 and
0.5.2. However, removing the interactive mode won't solve your problem. Without
command-line arguments, setup() will simply do nothig.
