automatically, but need to determine by the type of host Bash will run

on. Usually `configure' can figure that out, but if it prints a
|
||||
message saying it can not guess the host type, give it the
|
||||
`--host=TYPE' option. `TYPE' can either be a short name for the system

type, such as `sun4', or a canonical name with three fields:

||||
`CPU-COMPANY-SYSTEM' (e.g., `i386-unknown-freebsd4.2').
