Thanks for the quick fix, Brad.

Here's the next problem, in case you aren't tired of me yet:

C:\sf\ctypes\ctypes\wrap>type x.c
#include <limits.h>
int main()
{
    long long x = LLONG_MAX;
}
C:\sf\ctypes\ctypes\wrap>cl -c x.c
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.3077 for 80x86

x.c

C:\sf\ctypes\ctypes\wrap>\Programme\gccxml\bin\gccxml x.c
x.c: In function `int main()':
x.c:4: error: integer constant is too large for "long" type

C:\sf\ctypes\ctypes\wrap>

<limits.h> from MSVC7.1 contains:


/* Make sure these macros don't show up in ANSI C++ code */
#if !defined(__cplusplus) || defined(_MSC_EXTENSIONS)
#define LLONG_MAX     0x7fffffffffffffff  /*maximum signed __int64 value */
#define LLONG_MIN     0x8000000000000000  /*minimum signed __int64 value */
#define ULLONG_MAX    0xffffffffffffffff  /*maximum unsigned __int64 value */
#endif
