Lazy solution for me would be something like the following:
Does it look correct?
#if defined(__MINGW32__) && defined(__x86_64__)
#undef NtCurrentTeb
#define NtCurrentTeb MI_NtCurrentTeb
struct _TEB * MI_NtCurrentTeb(void) {
void *ret;
__asm__ __volatile__ ("movq %%gs:0x30,%0" : "=r" (ret));
return ret;
}
#elif defined(__MINGW32__) && defined(__i386__)
#undef NtCurrentTeb
#define NtCurrentTeb MI_NtCurrentTeb
struct _TEB * MI_NtCurrentTeb(void) {
void *ret;
__asm__ __volatile__ ("movl %%fs:0x18,%0" : "=r" (ret));
return ret;
}
#endif
