IsDebuggerPresent() function is not declared in Visual Studion 2005 and lower

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Create the simple test first_test.c:

#include <stdarg.h>
#include <stddef.h>
#include <setjmp.h>
#include "cmockery.h"

void main(void) {}

2. Put cmockery.h and cmockery.c to the same directory
3. Compile it: cl /I. first_test.c cmockery.c

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

- cmockery 0.1.2
- Visual Studio 2003, 2005 SP1, 2008
- Windows XP SP3

Please provide any additional information below.

Conclusion: Only starting from Visual Studio 2008 the function
IsDebuggerPresent() is declared in headers.

I use the following patch which explicitly declares the function
IsDebuggerPresent() for Visual Studio 2005 and lower:

This will be integrated into cmockery release 0.1.3.

just add

#define _WIN32_WINNT 0x0400

before

#include <windows.h>

may be a better methord.
