/* Global datastructures :
* - 'text_area' points to the text segment, 'text' points to first free
* entry in the text segment.
* - 'data_area' points to the data segment, 'data' points to the first free
* entry in the data segmnet.
* - 'string_area' points to the string area, 'string' points to the first free
* entry in the string area.
* - 'reloc_info' points to the relocation table, 'relo' points to the first
* free entry in the relocation table.
* - 'symbol_table' points to the symbol table, 'nname' is the index of the
* first free entry in the symbol_table. If pointers were used it is a pain
* to do a realloc on the symbol table, because all pointers in the
* relocation table to the symbol table have to be updated.
* - The bss segment contains only one vaue, so its enough to count the
* the bytes wanted.
* - The 'size_*' variables count the number of entries in each segment.
* - 'cur_seg' contains the number of the segment to be filled.
* (see "back.h")
