in_far = in_far;

in_far = in_far;

If it's just suppressing an unused variable warning, then how about:

(void)in_far;

I've had a lot of luck with that.

[memononen]

stb_image.c is external depencancy and I'd like to keep it as intact as possible so that it is easy to upgrade it later when necessary.

[andrewcorrigan]

I will contact upstream then

[memononen]

I think that is good idea to contact Sean.

On a second thought, since the change is so small, I think I'll merge it anyways. It should be easy to catch later if I need to update stb_image.

Contacted, thanks for merging it meanwhile, which allows me to avoid diverging from upstream
