I'm confused a bit by what you want to accomplish. Except for variable length arrays, isn't sizeof always evaluated at build time? 6.5.3.4 The sizeof operator Constraints [] 2 The sizeof operator yields the size (in bytes) of its operand, which may be an expression or the parenthesized name of a type. The size is determined from the type of the operand. The result is an integer. If the type of the operand is a variable length array type, the operand is evaluated; otherwise, the operand is not evaluated and the result is an integer constant.
