I am new to clang and I have tried to compile a simple application to test the
analysis functionnality of this compiler.

I have built the compiler as specified in
http://clang.llvm.org/get_started.html without any problem.

After that, I have tried to compile a simple example to verify that the
compiler works fine on my machine.

This is the file (file.c) :
#include <stdlib.h>

int main(void)
        int * p;

        p = malloc(100);
        if(p == (void *)0) free(p);

        p[0] = 10;

        return p[101];

The command line is as follow :
 clang-cc -DWIN32 -D_DEBUG -D_CONSOLE file.c -analyze

The result of the execution is :

In file included from file.c:1:
In file included from C:\Program Files\Microsoft Visual Studio
C:\Program Files\Microsoft Visual Studio 9.0\VC\include/crtdefs.h:562:9: error:
unknown type name '__int64'
typedef __int64 __time64_t;     /* 64-bit time value */
In file included from file.c:1:
C:\Program Files\Microsoft Visual Studio 9.0\VC\include/stdlib.h:384:9: error:
nknown type name '__int64'
        __int64    __cdecl _abs64(__int64);

The type __int64 is not known by the compiler.

Is it possible to support this variable type ?

I am very interresting to test the analysis functionnality of this compiler.
