In src/include/port/win32.h, we have this:

/*

 * our errcode() function.  Since it's likely to get included by standard
 * system headers, pre-emptively include it now.

#if _MSC_VER >= 1400 || defined(HAVE_CRTDEFS_H)
#define errcode __msvc_errcode
#include <crtdefs.h>
#undef errcode
#endif

For some reason, that doesn't seem to be working as intended, on your system. Do you see the above in src/include/pg_config_os.h ?

What version of Visual Studio or Platform SDK are you using? What is the value of _MSC_VER on your system?
