Most distros have that feature enabled by default. I've pointed out 
patent issue ever since I put the instruction there, but it seems no one 
reads "Command Explanations"

Command Explanations

--enable-texture-float: This switch enables floating-point textures and 
render buffers. Please consult docs/patents.txt to see if there are any 
legal issues if you use this feature.

Patents do not pose a problem outside of US and Germany today, even 
tough many countries claim to have that law. These are ones that "care 
the most".




Debian, Ubuntu and Archlinux seem to enable that flag by default and 
shipt it, while Gentoo does not even provide a way to enable it by 
default in portage.

I don't think that this might be patent infrigment from the user side, 
but from the developer side - implementing patented stuff into software 
that has not been granted permissions to do so.

Another story was S3TC stuff. I tought about adding an external library 
that implements S3 Texture Compression (libtxc_dxtn library) into Mesa 
instructions, but I didn't do that.
