I am not able to reproduce this issue on my Windows or Linux box. Have
you deleted Util.c and SPI.c files before starting with the build? The
point is, these files are generated during build time and if they
already exist then i think. they are not re generated. I would suggest
to delete both the .c files and rebuild your source and then give a
try.

Here are the results i got on Windows and Linux respectively on HEAD,

On Windows:
