Do not include config_win.h!
That's all.
- Use a current developer package. This package doesn't contain the
config_win.h file any more.
- Do not define BRLCADBUILD or HAVE_CONFIG_H. (This would switch the
config_win.h on in common.h.)
- You might have to define USE_PROTOTYPES. This define can be set
right before a BRL-CAD header include. (You probable don't need this
with version 7.12.6. BTW, I can't recommend setting the /Za compiler
option. The MS Windows SDK won't go with it.)
- You have to define BRLCAD_DLL as before.

Look at the MSDN Libray for "_write".
A work around for this problem e.g. for other libraries may be to
redefine the function for C++:
#define write _write
#ifdef __cplusplus
# undef write
inline int write(~) {
return _write(~)
}
#endif

Daniel
