Um, I'd suggest not using asm/types.h at all. __s64 and __u64 don't seem to 
follow any standard. Better use the types defined in sys/types.h

I wonder where these types are used in kdemultimedia? It just doesn't seem to 
be portable. And of course, if something in KDE uses long long, it's not 
strictly ANSI compliant and the build system should take care of this.
