Stefan Farfeleder 39376f45e2 - Fix bugs where the value of arithmetic expansion$((...)) was trucated
to type int.
- Change the type used for arithmetic expansion to intmax_t (ie. 64 bit on all
  currently supported FreeBSD architectures).  SUSv3 requires at least type
  long but allows for larger types.  Other shells (eg. bash, zsh, NetBSD's sh)
  do that too.
