Early Roguelike Collection: arogue7/maze.c annotate

annotate arogue7/maze.c @ 197:61d1c9ac9be7

Advanced Rogue 5: rearrange some of mdport.c. process.h is now included in the proper place for compiling with MSVC. md_sleep() has been removed. If it were used anywhere, it could have been fixed by replacing _sleep() with Sleep().
