But some include files include <machine/ansi.h> and not <sys/cdefs.h>, or include both in the wrong order (<sys/cdefs.h> after <machine/ansi.h>). Affected files are: <err.h> <inttypes.h> <netdb.h> <stddef.h> <string.h> <syslog.h> <time.h> <vis.h> <sys/dirent.h> <sys/inttypes.h> <sys/queue.h> <sys/syslog.h> <sys/times.h> At least for <inttypes.h>, <stddef.h>, <string.h> and <time.h>, this is contrary to ISO 9899:1999, aka the C standard, which specifies (in 7.1.2/4) that "standard headers may be included in any order". >How-To-Repeat: Preprocess the following one-line code with `gcc -E' or another standard preprocessor: #include <stddef.h> you will find in the output the faulty declaration with `__signed'. >Fix: Fix the above-stated include files to include <sys/cdefs.h> before <machine/ansi.h>. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
