rgb_cam ?

From the documentation section :

float rgb_cam[3][4];
Another white balance matrix, read from file for Leaf and Kodak cameras.

Isn't rgb_cam the color profile to transform from camera color spave to srgb color space?



You're right, these comments

You're right, these comments are very outdated (from very old dcraw source code).
For now, cmatrix and rgb_cam are used to color conversion too.
