<stdarg.h> file and also includes the OS4-specifc <sys/amigaos-va.h> file, if necessary. - Added another test to <sys/time.h> to check if the "timeval" definition is already in place. If it is, <exec/types.h> will not be included. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14720 87f5fb63-7c3d-0410-a384-fd976d0f7a62
