compile with gcc -Werror=format

Hi.
I'm compiling my project with -Werror=format and compilation failt when I use
bit fields of (u)int64_t type. I expected that bit fields wider than 32 bits
will be compatible with PRIu64/PRIi64/PRIx64.
This bug also appears in 4.8 branch (don't know about earlier versions).
