Last change on this file since 71eef11 was 71eef11, checked in by Martin Decky <martin@…>, 17 years ago

remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
