License of libswscale

I read, that the shared libray libswscale is published under the terms of the GPL. I had a look on the source code and saw that the most source code is LGPL. But the opimization for MMX and so on is GPL.

Well, I wonder if it is possible to comiple a LGPL version of the libswscale library.

Edit 2010-01-23:
It seems, the the whole FFmpeg library is LGPL if it is compiled with the option
--enable-shared
and without the options
--enable-static --enable-gpl
