 *

 *  or32 version

 *

 * This program is used to generate definitions needed by

 * assembly language modules.

 *

 * We use the technique used in the OSF Mach kernel code:

 * generate asm statements containing #defines,

 * compile this file to assembler, and then extract the

 * #defines from the assembly-language output.
