recursive inclusion

In Ivanhoe, file "low_depth.c", there is "#include "low_depth.c"". The file recursively includes itself. Why?
Is this just sloppy programming?
And, other Ivanhoe files do this.

I think they just outsmarted themselves.
There is an include guard that makes the second inclusion different from the first, so the code is compiled once for white and once for black. Doing that in a single file is just too cute, if done on purpose, or just silly if they didn't some up with the idea of having two .c files (low_depth_black and low_depth_white) that include a common set of .h files.
