ODBC requires <windows.h> to be included before.

ULONG is a Windows specific type.

It seems the <sqltypes.h> re-typedef's several types using the typical 
windows type name vs the standard type names.
eg:
    typedef ULONG UDWORD;
instead of:
    typedef  uint32_t UDWORD;

So, your options are to either re-write sqltypes.h to use the standard 
type names, or to include <windows.h> prior to including <sqltypes.h>, 
or at least including <windef.h>.

---------------------------

#include <iostream>
#include <windef.h>
#include <sqltypes.h>

int main () {
	return 0;
}
---------------------

Most Windows API headers are not designed to be included individually, so
try adding #include <windows.h> before the other headers you want to
include. MinGW GCC 3.2 had a problem with it automatically including
windows.h, so the fact that it worked that way was accidental. Do not
specify standard include directories on the command line.

Do you need to add '.h' to the end of that header's name?

Of cource!

It was a writing mistake.

The write one (which is in my code) is <sqltypes.h>.
