Windows 빌드 실패 가능성: 미선언 함수 호출

query_cancel_process()가 #if !defined(WINDOWS) 가드 없이 호출되고 있으나, cas_common_main.h에서의 선언은 #if !defined(WINDOWS) 블록 내부에만 있습니다. Windows 빌드에서는 함수 선언이 보이지 않아 C99 기준으로 implicit function declaration 오류가 발생합니다. cas_common_main.c에 Windows 스텁(assert(0))이 존재하더라도, 헤더에 선언이 없으면 컴파일러가 이를 거부합니다.

큐브리드는 윈도우 빌드를 더이상 지원하지 않으므로 상관 없음.
