/*
 * The executable's .bss that no module can hold. The modules leave these
 * variables uninitialized (static in -G8 units), so maspsx emits them as
 * common symbols, and the original's linker laid the commons out 8 bytes
 * apart in link order; GNU ld would lay them out its own way, so these
 * definitions, in a unit whose commons maspsx turns into .bss (see the
 * Makefile), fix the original's addresses. CD_SECTOR_HEADER, the .bss of
 * file/cd_reader.c, stays with them: defining it there needs maspsx to turn
 * that unit's commons into its own sections, CD_MODE with them, which would
 * take CD_MODE out of the commons around it.

/*
 * 2MBYTE.OBJ's .bss, where its startup code, crt0, keeps $ra across InitHeap;
 * the second word is unused. Defined here, at the start of the .bss, so its
 * bytes stay in a report unit.
