Summary:
In Microsoft C versions 5.0, 5.1, 6.0, 6.0a, and 6.0ax, the pack
pragma affects declarations; not definitions. Place #pragma pack()
prior to data declarations.
More Information:
The following program demonstrates usage of #pragma pack():
/* Elements of variables of type struct x will be byte-aligned. */
#pragma pack(1)
struct x { int a; char b; int c; };
/* Elements of variables of type struct y will be word-aligned. */
#pragma pack(2)
struct y { int a; char b; int d; };
/* The pragma below does NOT affect the definitions that follow. */
#pragma pack(4)
struct x X;
struct y Y;
void main (void)
{ /* dummy main */ }
