Hey, that's a nice obfuscation of a simple negation.

It's not a negation.  This statement always assigns zero to
dri_data[5] if dri_data is char[].  Looks like gcc isn't catching
this problem.

BTW, when assigning to a char type, is the masking really necessary at
all?  I can't see that it should make a difference.  Am I missing
something subtle?

Well, it's a matter of readability mostly.  For now at least, when
char is always 8 bytes...
