libcpp: Fix overly large buffer allocation
It seems that tokens_buff_new() has always been allocating the virtual
location buffer 4 times larger than intended, and now that location_t is
64-bit, it is 8 times larger. Fixed.
libcpp/ChangeLog:
* macro.cc (tokens_buff_new): Fix length argument to XNEWVEC.
