[texworks] Building TeXworks on Windows using MinGW

OK I modified KDEDIRS and did suppress the part which was pointing to 
KDE msvc in the path.
qmake is now the mingw one

There is no Qt\4.4.3\src directory, but I did find qatomic_windows.h in 
\include\Qt and \include\Qtcore
In these files there is no:
/*#if !(defined Q_CC_BOR) || (__BORLANDC__ < 0x560)   
extern "C" {
__declspec(dllimport) long __stdcall InterlockedCompareExchange(long *, 
long, long);   
__declspec(dllimport) long __stdcall InterlockedIncrement(long *);   
__declspec(dllimport) long __stdcall InterlockedDecrement(long *);
__declspec(dllimport) long __stdcall InterlockedExchange(long *, long);   
__declspec(dllimport) long __stdcall InterlockedExchangeAdd(long *, 
long);   
}   
#else */
extern "C" {   
__declspec(dllimport) long __stdcall InterlockedCompareExchange(long 
volatile*, long, long);   
__declspec(dllimport) long __stdcall InterlockedIncrement(long 
volatile*);   
__declspec(dllimport) long __stdcall InterlockedDecrement(long 
volatile*);   
__declspec(dllimport) long __stdcall InterlockedExchange(long volatile*, 
long);   
__declspec(dllimport) long __stdcall InterlockedExchangeAdd(long 
volatile*, long);   
}   
// #endif

but only the first part (here the commented part); so I modified the 
existing part to have "long volatile*"
I did this in both files !!!!

Now compilation is different, it goes long before to end with errors.
In the attached files you'll find what is output in the redirection file 
(compil.log) and what is not redirected but goes immediately to the 
console (mingw32-make_compilation.log)
