Thanks for your reply.
Although there's no 'clean' method, do you know how can I make the
#pragma work?
I've seen some macros I could define but none of them work: here we go:
#define HANDLE_PRAGMA 1
#define HANDLE_SYSV_PRAGMA 1
#define BIGGEST_ALIGNMENT 8
#define BIGGEST_FIELD_ALIGNMENT 8
#define STRICT_ALIGNMENT 1
