By misuse, I mean using the file generated for another architecture, esp. when size of GoInt differs.

Two possible solutions:

  1. Add #ifndef __x86_64__ and #error to make sure it is only built with the correct platform. Or we can relax a bit and check for sizeof(GoInt) == sizeof(void *).
  2. Define size of GoInt to be sizeof(void*). This is true for all supported platforms.

Opinions?
