You have found the solution yourself:

#ifdef WIN32
/* windows stuff */
#else
typedef unsigned long DWORD;
typedef unsigned short WORD;
typedef unsigned int UNINT32;
#endif

Put this in a separate header file (typedefs.h) and include it from everywhere. Typedef are always preferred over pre-processor macros.

My recommendation: Do not use DWORD, WORD or other Win32 types. I usually prefer to use C99 standard types: uint_t, int_t or uint16_t, uint32_t
