  At the top of the program put this line:-

#define pk __attribute__((packed))

  Then, when you declare the struct or class, insert the word pk next before
every `;' that comes at the end of a member declaration, e.g.:-

typedef struct{long di,si,bp,res,bx,dx,cx,ax pk;
    short flags,es,ds,fs,gs,ip,cs,sp,ss pk;} Regs;
class dirbuf{public:byte Reservebuf[21],attrib pk; FCBtime time pk;
    FCBdate date pk; uns long size pk; char name[13] pk;
    dirbuf();
    byte GetFirst(char*dirname, uns int attrib=~0);
    byte GetNext();
    int get(char*name);};
