Compilation problems - Linux Mint 17.3

I'm trying to compile KMQuake2 from this repo, and I have this output error in r_image.c

Any ideas how to solve this?

Not really, I haven't looked into it for a long time.
What compiler and OS do you use?

OS - Linux Mint 17.3 Cinnamon (cannot update to 18.x because I use an ATI graphic card)
CC - gcc 4:4.8.2-1ubuntu6
