Well, the compilation issues have been found and partially fixed by
Guillaume Letellier. On a positive side, this breakage was a good
chance for more people who are interested in ARM platform support
to come out of the shadow :-)

Still one more fix is needed to solve the compilation problems (patch
is attached).

More serious is a problem with the newly added functions 
fbCompositeSolid_nx0565neon and fbCompositeOver_8888x0565neon.
They are quite broken. And (not a) surprise - this breakage
can be easily spotted by all the same 'scaling-test' program.

Jonathan, could you please have a look and try to fix these issues?

But for now it is a good idea to either comment them out or
revert the patches.

Best regards,
