 18 Host Configuration
 *********************
 
 Most details about the machine and system on which the compiler is
 actually running are detected by the `configure' script.  Some things
 are impossible for `configure' to detect; these are described in two
 ways, either by macros defined in a file named `xm-MACHINE.h' or by
 hook functions in the file specified by the OUT_HOST_HOOK_OBJ variable
 in `config.gcc'.  (The intention is that very few hosts will need a
 header file but nearly every fully supported host will need to override
 some hooks.)
 
  If you need to define only a few macros, and they have simple
 definitions, consider using the `xm_defines' variable in your
 `config.gcc' entry instead of creating a host configuration header.
