Question: Since upgrading 'everything' today to deploy to OS4 devices, it no longer recognizes localized XIBs and plists. (It=neither iPhone simulator or iPhone.) As in, before OS4, switching language caused the correct localized files to be loaded, but not so now. Does something need to be 'recreated', 'nudged', or renamed? It has worked on simulator and devices since April, and I get no warnings in my code.

The languages are English and sv\_SE, in case there has been a change in language codes.

Answer: 
For the 64-bit:

```
#include <inttypes.h>
typedef int64_t __int64;

```

As for the TCHAR problem. I actually find TCHARs rather useful so I have a file with all the \_t functions I use in it.

e.g

```
#ifdef UNICODE 

#define _tcslen     wcslen
#define _tcscpy     wcscpy
#define _tcscpy_s   wcscpy_s
#define _tcsncpy    wcsncpy
#define _tcsncpy_s  wcsncpy_s
#define _tcscat     wcscat
#define _tcscat_s   wcscat_s
#define _tcsupr     wcsupr
#define _tcsupr_s   wcsupr_s
#define _tcslwr     wcslwr
#define _tcslwr_s   wcslwr_s

#define _stprintf_s swprintf_s
#define _stprintf   swprintf
#define _tprintf    wprintf

#define _vstprintf_s    vswprintf_s
#define _vstprintf      vswprintf

#define _tscanf     wscanf

#define TCHAR wchar_t

#else

#define _tcslen     strlen
#define _tcscpy     strcpy
#define _tcscpy_s   strcpy_s
#define _tcsncpy    strncpy
#define _tcsncpy_s  strncpy_s
#define _tcscat     strcat
#define _tcscat_s   strcat_s
#define _tcsupr     strupr
#define _tcsupr_s   strupr_s
#define _tcslwr     strlwr
#define _tcslwr_s   strlwr_s

#define _stprintf_s sprintf_s
#define _stprintf   sprintf
#define _tprintf    printf

#define _vstprintf_s    vsprintf_s
#define _vstprintf      vsprintf

#define _tscanf     scanf

#define TCHAR char
#endif

```

as for the \_s functions basically ... I implemented them. It takes about an hour of coding to do but it makes porting projects to other platforms or compilers IMMENSELY easier.
GCC supports `long long` (depending on compilation flags), which is a 64-it integer. Or you can use `std::int64_t` from the `cstdint` header.

Or to be more cross-platform, use `boost/cstdint.hpp`, which defines `boost::int64_t`

`_tmain` is just Microsoft being silly (or nonstandard, if you will) The rest of the world uses `main`, plain and simple.
`_TCHAR` has no direct equivalent, but since you say you don't need to support `wchar_t`, you can just replace it wit `char`.
