Index of solutions to get features hidden because of patents.
I would like this topic to be a place find all the compile-time flags, environment variables, external libraries etc. which hide the patented features, like S3TC compression or floating point textures.

If it's not ready for production use, then it's not ready to be posted here, OK?
Floating point textures:
S3TC compression algorithm:
This is list is information resource for people living in countries, where software patents are not in force.
