During porting a piece of a DOS program to make a driver
for FreeBSD of it for a certain device I'm stuck at the
point where there is a structure:
struct C_OPEN {
int a;
int b;
unsigned xdt:1;
unsigned reserved:15;
}
The sizeof this structure is 10 under DOS (borland C)
and evaluates to 12 under cc (gcc) on FreeBSD.
There are a lot of these definitions and it would be
tedious to find a workaround.
Does anyone know if I can pack the structure respectively
enforce the bitfield to a short int?
