Why does this TinyOS C code file appear obfuscated?

Question

I've received a 2 MB code file for a device based on TinyOS and it appears that some application has consolidated all of the original code files into one but it moves lines all around. Do you know what generated this file and how to extract it?

Here's the first couple hundred lines of the app.c provided:

#define dbg(mode, format, ...) ((void)0)
#define dbg_clear(mode, format, ...) ((void)0)
