Have not reviewed it in detail, but some comments:

1. don't change whitespace (eg blank lines, that just makes noise in
the patch that is not needed making real review harder)
[Shankhoneer] Point noted. I will remove these noises in my patch 
 
2. don't use doxygen comments for in-code comments
[Shankhoneer] I have changed all in-code doxygen comments to c-style comments 
3. watch the layout, you are missing many spaces after commas
[Shankhoneer] Fixed this too 
4. is setting a pointer to a piece of the string and comparing it to
"warning" really the best way of returning that information rather
than a bool or enum?
[Shankhoneer] I dont understand exactly what you are trying to suggest. Do you mean that I should create a function that returns which color the line should be given the error message? I have never used C before in production software as big as geany so please feel free to comment directly what would be a better approach.
5. compiler lines are also parsed by filetypes_parse_compiler_line()
[Shankhoneer] I couldnt find filetypes_parse_compiler_line() but I found filetypes_parse_error_message() in filetypes.c

The preferred way of providing changes is now via pull requests on
github rather than patches.  The HACKING needs updating.
[Shankhoneer] I have forked the project and working on the forked repo.

See also #907 :-D
[Shankhoneer] Woah! #907 is like a long TODO list for C++11. I have started to look into some of the issues like 5e. 

Thanks,
