These are all part of the Microsoft basetsd.h file:

typedef signed char         INT8, *PINT8;
typedef signed short        INT16, *PINT16;
typedef signed int          INT32, *PINT32;
typedef signed __int64      INT64, *PINT64;
typedef unsigned char       UINT8, *PUINT8;
typedef unsigned short      UINT16, *PUINT16;
typedef unsigned int        UINT32, *PUINT32;
typedef unsigned __int64    UINT64, *PUINT64;

I have not deliberately excluded mingw from being supported, but as the
Microsoft compilers are freely available in .Net SDKS, then I could not
see the point of anyone using mingw anymore to be honest, so I put it
aside. Mingw should really have those typedefs though - see thousands of
Google hits on people complaining about this.

stdint.h may be supplied with mingw, but it is not a part of the windows
headers. However, I think that Mingw defines: __MINGW32__ if it is the
compiler, so if stdint.h is always present when mingw is the compiler,
which I believe is the case, then I can modify the headers for mingw.

I thought that mingw was designed to compile windows code - hence you
need to run configure on cygwin, but not if using mingw as the
antlr3config.h is not required in Windows systems.

I have changed the headers to reflect Mingw support - perhaps you can
ask the people that support mingw to update their typedefs?
