 *
 *
 * v0.7 (02.01.98) phx
 *      Option -O (output format) was renamed to -F. New option -O for
 *      enabling optimizations. Changed "1997" to "1997-98".
 *      Output format 3 is ADOS (like EHF, but doesn't use HUNK_PPC_CODE).
 * v0.6 (30.10.97) phx
 *      Description for option -R was changed from "don't predefine
 *      standard symbols" into "don't predefine register symbols".
 *      Options to disable warnings for optional, 64-bit and super-
 *      visor instructions: -mo, -m64, -ms.
 * v0.5 (12.10.97) phx
 *      New option -D to define a symbol.
 * v0.4 (02.07.97) phx
 *      -V prints only version and build string and no instructions. New
 *      function show_version().
 *      Base address for absolute code may be set with -B option.
 *      New option -I to specify some include paths.
 *      Option -x automatically declares unknown symbols as
 *      externally defined.
 * v0.3 (26.03.97) phx
 *      New option -O to select output file format.
 * v0.2 (25.03.97) phx
 *      Writes ELF object for 32-bit PowerPC big-endian. Either absolute
 *      or ELF output format may be selected. ELF is default for all
 *      currently supported platforms. PPCasm supports nine different
 *      relocation types (there are much more...).
 *      Compiles and works also under NetBSD/amiga (68k).
 *      Changed function declaration to 'new style' in all sources
 *      (to avoid problems with '...' for example).
 * v0.1 (11.03.97) phx
 *      First test version with all PowerPC instructions and most
 *      important directives. Only raw, absolute output.
 * v0.0 (14.02.97) phx
 *      File created. Project started.
