Code only checks if 4 bytes for `rawptr` size. However lua defines the macro (that I assume the odin code is based on) as:
```
/*
@@ LUAI_IS32INT is true iff 'int' has (at least) 32 bits.
*/
#define LUAI_IS32INT ((UINT_MAX >> 30) >= 3)
```
This error broke `upvalues` because it would be looking for the wrong index for lua to find them at.
From some testing with directly using C code, pthread_t on macos is 8 bytes.
This is my test code:
```
#include <assert.h>
#include <stdio.h>
#include <pthread.h>
void* PosixThreadMainRoutine(void* data)
{
// Do some work here.
for (int i = 0; i < 2000000000; i++) {
}
return NULL;
}
pthread_t LaunchThread()
{
// Create the thread using POSIX routines.
pthread_attr_t attr;
pthread_t posixThreadID;
int returnVal;
returnVal = pthread_attr_init(&attr);
assert(!returnVal);
returnVal = pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_JOINABLE);
assert(!returnVal);
int threadError = pthread_create(&posixThreadID, &attr, &PosixThreadMainRoutine, NULL);
returnVal = pthread_attr_destroy(&attr);
assert(!returnVal);
if (threadError != 0)
{
// Report an error.
}
return posixThreadID;
}
int main() {
pthread_t t = LaunchThread();
void ** ret;
printf("%d, %d\n", sizeof(t), sizeof(pthread_t));
int val = pthread_join(t, ret);
printf("%d", val);
return 0;
}
```
running this on macos reports `8, 8`.
Then I made the proposed changes and errors I was having with threads completely went away.
The stat struct was the format for the 64 bit version of stat. So we need to call stat64 to get the proper data.
Also we need to use _File_Time instead of File_Time because it is a compound value.
These changes were tested and work on my computer, MacOS 64 bit.
