Define the specific structure you want with the gcc-specific syntax 
__attribute__((packed).  You do that like this:

struct foo {
  char a;
  short b __attribute__((packed));
  int c __attribute__((packed));
};

I think you can also put the attribute on the structure itself (after the 
closing {}) to pack all fields together.

Variable attributes in gcc are described here:
