/*
 * genassym.c is used to produce an
 * assembly file which, intermingled with unuseful assembly code,
 * has all the necessary definitions emitted. This assembly file is
 * then postprocessed with sed to extract only these definitions
 * and thus the final assyms.s is created.
 *
 * This convoluted means is necessary since the structure alignment
 * and packing may be different between the host machine and the
 * target so we are forced into using the cross compiler to generate
 * the values, but we cannot run anything on the target machine.
