Several long-awaited updates for the Macintosh port, by Dean Luick and myself. This set affects Mac-only files. * Update the support for MPW compilers. * Use new system call names provided for in the latest Apple Universal Headers. * Tune up some of the includes for CodeWarrior. * Define YY_NEVER_INTERACTIVE for the dungeon and level compilers. * Remove pointless debugging code. * Clean up some unterminated comments.
