It's just a single .c file in the project. Here's the code:
#define WIN32_LEAN_AND_MEAN
#include <Windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <process.h>
#include <tchar.h>
typedef struct _Configuration
{
int KeyActivate;
int BlockWidth;
int BlockHeight;
double HueStart;
double HueEnd;
double SaturationStart;
double SaturationEnd;
double ValueStart;
double ValueEnd;
} Configuration;
typedef struct _DIBSection
{
HDC ScreenDC;
HDC WindowDC;
HDC MemoryDC;
HBITMAP ScreenBMPHandle;
BITMAP ScreenBMP;
} DIBSection;
typedef struct _Thread
{
HANDLE Handle;
unsigned Id;
} Thread;
typedef struct _Window
{
HANDLE Handle;
HDC DC;
int Width;
int Height;
int Top;
int Left;
} Window;
__declspec ( dllexport ) int Initialize ( void );
unsigned __stdcall Start ( void * Arguments );
void LoadDefaultConfiguration ( Configuration * Config );
bool SaveConfiguration ( Configuration * Config, LPTSTR FilePath );
bool LoadConfiguration ( Configuration * Config, LPTSTR FilePath );
Thread MainThread;

BOOL WINAPI DllMain ( HINSTANCE Instance, DWORD Reason, LPVOID Reserved )

switch ( Reason )
{
case DLL_PROCESS_ATTACH:
// TODO: Load settings from file

// Create main thread
MainThread.Handle = (HANDLE) _beginthreadex (

}
else
{

}
break;

}
return TRUE;
}
__declspec ( dllexport ) int Initialize ( void )

}

}
void LoadDefaultConfiguration ( Configuration * Config )
{
Config->BlockHeight = 50;
Config->BlockWidth = 100;

}
bool SaveConfiguration ( Configuration * Config, LPTSTR FilePath )
{
return true;
}
bool LoadConfiguration ( Configuration * Config, LPTSTR FilePath )
{

}
Line 51 is
bool SaveConfiguration ( Configuration * Config, LPTSTR FilePath );

Answer 1

bool is not a C type.
I do suspect BOOL is defined somewhere.
Same goes for the usage of true and false.

Answer 2

Actually, bool is a valid type (well, a macro actually) in the C99 standard, assuming you are using a recent compiler. You need to add:
#include <stdbool.h>
Note that bool is not valid in the older ANSI, C89, C90 etc variants of the C standards.
As highlighted by JeremyP in the comments, Microsoft's C compiler still lacks proper support for C99 features.
Which leaves three alternatives:
Treat it as C++, not C; because C++ has bool as a built-in type
Create your own bool implementation
Re-write the code to avoid using bool
For option 2 something like this would work, but it's an ugly work-around:
typedef short bool;
#define true 1
#define false 0
