It's better to make the script generate properties:
public static int O_EXCL {
get {return 0xwhatever;}
}
The jit will inline the call and constant-fold if you use multiple
options (it cannot do that if you pinvoke a function).
Using properties still allows to have separate values on different
platforms without having a C library at runtime.
