[Mesa-dev] [PATCH 0/4] import the txc_dxtn code from libtxc_dxtn into mesa (Was: Merge floating to master)

[Corbin Simpson]

--enable-float-formats should be fine.

Stop messing with S3TC. I think things like my previous attempt to
language-lawyer S3TC compatibility in without any patented code are a
better use of time than silly patches to shoehorn it in to the
detriment of the rest of us.
