Bruce Evans a09bee1aa8 Fixed pedantic semantics errors (bitfields not of type int, signed int 
or unsigned int (this doesn't change the struct layout, size or
alignment in any of the files changed in this commit, at least for
gcc on i386's.  Using bitfields of type u_char may affect size and
alignment but not packing)).
