Bug ID: 57672 Summary: va_list fixinclude needed for AIX 5.3 sys/types.h Product: gcc Version: 4.8.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: chasonr at newsguy dot com On AIX 5.3, the system file /usr/include/sys/types.h contains this declaration: #ifndef _VA_LIST #define _VA_LIST typedef char * va_list; #endif This conflicts with the fixincluded va_list in stdarg.h. va_list needs to be declared as __builtin_va_list. GCC 4.8.1 already performs other fixincludes for sys/types.h.
