<sys/featuretest.h> defines _NETBSD_SOURCE if any other
_XXXX_SOURCEs are not defined.
<sys/featuretest.h>:
65 #if !defined(_ANSI_SOURCE) && !defined(_POSIX_C_SOURCE) && \
66 !defined(_XOPEN_SOURCE) && !defined(_NETBSD_SOURCE)
67 #define _NETBSD_SOURCE 1
68 #endif
And <sys/types.h> defines u_char only if _NETBSD_SOURCE is
defined.
<sys/types.h>:
100 #if defined(_NETBSD_SOURCE)
101 typedef unsigned char u_char;
102 typedef unsigned short u_short;
<stdlib.h> includes <sys/featuretest.h> and <sys/types.h> again.
An inconsistency comes here, because _XOPEN_SOURCE is already
undefined in ssl/kssl.c.
<stdlib.h>:
38 #include <sys/featuretest.h> <== _NETBSD_SOURCE is defined
39
40 #if defined(_NETBSD_SOURCE)
41 #include <sys/types.h> <== disabled by _SYS_TYPES_H_
42 #endif
...
236 #if defined(_NETBSD_SOURCE)
...
244 void arc4random_stir(void);
245 void arc4random_addrandom(u_char *, int); <== error!
246 char *getbsize(int *, long *);
In fact, <sys/featuretest.h> doesn't define guarding macro
(e.g. _SYS_FEATURETEST_H_), so _NETBSD_SOURCE could be defined at
the second include :-(
It may be an issue of NetBSD, but "#undef _XOPEN_SOURCE"
seems a little wrong too.
