I recently took your solution to fixing the watt32 sys/cdefs.h file and 
it was building properly (the version publically available on watt32 site).

Like you mentioned, you have to use gcc 4 as 5 has issues with multiple 
extern defines.
After that, and using Ozkan's solution of changing ioctl to ioctlsockets 
q2dos will now build properly in 2.05 with GCC 4.84.
