  1. /*
  2.  * ARCH_INCLUDE.h -- helper macro for including architecture specific
  3.  * header files.
  4.  *
  5.  * Usage:
  6.  *    #import    ARCH_INCLUDE(prefix_dir/, suffix.h)
  7.  * Where:
  8.  *    ARCH_INCLUDE(prefix_dir/, suffix.h)
  9.  * produces (for m68k architecture):
  10.  *    "prefix_dir/m68k/suffix.h"
  11.  *
  12.  * NOTE: prefix_dir, if non-null, must end with a '/'
  13.  *
  14.  * Current deficiency: can't specify <...>, only "...".
  15.  *
  16.  * __TARGET_ARCHITECTURE__ may be defined to specify a different
  17.  * different architecture that the compiler is generating code for.
  18.  * Define __TARGET_ARCHITECTURE__ as a string, e.g.:
  19.  #    #define    __TARGET_ARCHITECTURE__    "m68k"
