컴파일 에러좀 잡아주세요..^^

이 소스를 test.c 로 변경해서 컴팡리 할 경우는
gcc -c test.c
In file included from test.c:6:
/usr/include/sys/strsubr.h:174: field `sd_pollist' has incomplete type
test.c: In function `main':
test.c:14: storage size of `l_stIpcs' isn't known
test.c:15: storage size of `l_stTcps' isn't known
이런 에러가 납니다.

해결책 좀 알려주시면 감사하겠습니다...
