 6.2 Canadian Cross Concepts
 ===========================
 
 When building a Canadian Cross, there are at least two different systems
 involved: the system on which the tools are being built, and the system
 on which the tools will run.
 
    The system on which the tools are being built is called the "build"
 system.
 
    The system on which the tools will run is called the host system.
 
    For example, if you are building a Solaris program on a GNU/Linux
 system, as in the previous section, the build system would be GNU/Linux,
 and the host system would be Solaris.
 
    It is, of course, possible to build a cross compiler using a Canadian
 Cross (i.e., build a cross compiler using a cross compiler).  In this
 case, the system for which the resulting cross compiler generates code
 is called the target system.  (For a more complete discussion of host
 and target systems,  Host and Target).
 
    An example of building a cross compiler using a Canadian Cross would
 be building a Windows cross MIPS ELF compiler on a GNU/Linux system.  In
 this case the build system would be GNU/Linux, the host system would be
 Windows, and the target system would be MIPS ELF.
 
    The name Canadian Cross comes from the case when the build, host, and
 target systems are all different.  At the time that these issues were
 all being hashed out, Canada had three national political parties.
