You could have said that before i started to work on droping the old
scaler. I do not really disagree that a plain ./configure should not fail
but this leads to a deadlock because
1. swscale depends currently on a yuv2rgb table generator
2. ive no intent and made it clear in the past that i will not rewrite the
gpl yuv2rgb table generator
3. noone else works on swscale, ignoring 2-3 small patches
I thought it was agreed in the droping of the old scaler thread that whoever
wants a lgpl scaler will have to do the work.
And i suspect that noone will do this work when the old scaler is still in
svn, even less so when it is default.
