Several compilers offer "long long" without claiming to support C99.

Considering how frequent __s64/__u64 are used our userspace headers are anyway unusable without __s64/__u64 available.

Always offer __s64/__u64 to non-gcc non-C99 compilers - if they provide "long long" that makes the headers compiling and if they don't they are anyway screwed.

This makes sense to me (I did, however, not want to make that change part of the same changeset - one change at a time.)

The main reason for not just blindly using "long long" has to do with the use of gcc -ansi -pedantic in userspace, which is already taken care of by the use of __extension__ in the __GNUC__ clause.
