Small correction to the testcase, the problem is without any feature test macros actually. In file included from a.c:2: /usr/include/sys/wait.h:67: error: conflicting types for â??__WAIT_STATUSâ?? /usr/include/stdlib.h:72: note: previous declaration of â??__WAIT_STATUSâ?? was here In file included from /usr/include/sys/wait.h:80, from a.c:2: /usr/include/bits/waitstatus.h:68: error: redefinition of â??union waitâ??
