Summary: Cannot build STLPort Test units

Initial Comment:
Mingw tools installed and setup with the latest stable download mingw-5.1.6.exe.
When building STLPort 5.2.1 Test units, the following compilation errors occur:

.../winbase.h:1667: error: declaration of C function
`LONG InterlockedDecrement(LONG*)' conflicts with
.../_windows.h:167: error: previous declaration
`long int InterlockedDecrement(volatile long int*)' here

.../winbase.h:: error: declaration of C function
`LONG InterlockedIncrement(LONG*)' conflicts with
.../_windows.h:: error: previous declaration
`long int InterlockedIncrement(volatile long int*)' here

.../winbase.h:: error: declaration of C function
`LONG InterlockedExchange(LONG*)' conflicts with
.../_windows.h:: error: previous declaration
`long int InterlockedExchange(volatile long int*)' here

>From the Mingw mailing list, Keith pointed out that the error is due to non-conforming calling convention for some of the functions in winbase.h used by mingw as it relates to MSDN.

Keith quote:

"Looks like *some* of the Increment* function prototypes have been 
incorrectly declared in w32api's winbase.h; (MSDN says some should 
be __cdecl, but w32api declares all as WINAPI, (i.e. __stdcall))."
