Hi Bruno
The official name is NonStop Kernel.
Version number, hmm. There are several. First there are several different
architectures, TNS (outdated), TNS/R (Risc, mips, almost outdated) and TNS/E
(EPIC, Itanium). There's also NEO or Neoview, which basically is the same as
EPIC. Both come in 2 flavours, the newer of either is a blades architecture
OS versions are Cnn.mm (TNS), Dnn.mm (TNS/R, Hnn.mm and Jnn.mm (TNS/E), Nnn
and Pnn (NEO)
config.guess know only TNS/R. I've already submitted patches (to Ben
Eliston, resp. address@hidden) to also recognize TNE(E and Neo.
Here they go again:

__TANDEM is the predefined C compiler macro, __hpux is not (that an
different OS altogether)
Refencence for the ACL APIs should be here:

and here:

/usr/include/sys/acl.h is the header file
It contains a couple macros:
/* cmd values used by acl() */
#define ACL_GET 0x01 /* get ACL */
#define ACL_SET 0x02 /* set ACL */
#define ACL_CNT 0x03 /* get ACL Count */
/* cmd values used by acl_save_restore() */
#define ACL_GETALL 0x04 /* get ACL */
#define ACL_SETALL 0x05 /* set ACL */
#define ACL_CNTALL 0x06 /* get ACL Count */
A struct:
struct acl {
int a_type; /* entry type */
uid_t a_id; /* user or group ID */
unsigned short a_perm; /* entry permissions */
};
Some more macros:
/*
* Values for acl entry type (a_type field)
*/
#define USER_OBJ 0x01 /* owner of the object */
#define USER 0x02 /* additional users */
#define GROUP_OBJ 0x04 /* group of the object */
#define GROUP 0x08 /* additional groups */
#define CLASS_OBJ 0x10 /* file group class entry */
#define OTHER_OBJ 0x20 /* other entry */
#define ACL_DEFAULT 0x10000 /* default entry */
#define DEF_USER_OBJ (ACL_DEFAULT | USER_OBJ)/* default object owner */
#define DEF_USER (ACL_DEFAULT | USER) /* default additional users
*/
#define DEF_GROUP_OBJ (ACL_DEFAULT | GROUP_OBJ)/* default owning group */
#define DEF_GROUP (ACL_DEFAULT | GROUP) /* default additional groups
*/
#define DEF_CLASS_OBJ (ACL_DEFAULT | CLASS_OBJ)/* default class entry */
#define DEF_OTHER_OBJ (ACL_DEFAULT | OTHER_OBJ)/* default other entry */
#define NACLBASE 4 /* number of "base" ACL entries */
/* (USER_OBJ, GROUP_OBJ, */
/* CLASS_OBJ, & OTHER_OBJ) */
#define NACLENTRIES 150 /* Total number of base + optional entries,
*/
/* arbitrarily selected to match HFS's # of
*/
/* optional entries (HFS only has 3 base
*/
/* entries; cf. NACLENTRIES in <sys/acl.h>)
*/
#define DONTCARE 0x40000 /* for pattern match */
#define IDDONTCARE 0x80000 /* for pattern match */
/* For source compatibility with HPUX, the following two NACLV aliases
are provided: */
#define NACLVBASE NACLBASE /* For compatibility with HPUX */
#define NACLVENTRIES NACLENTRIES /* For compatibility with HPUX */
and some prototypes :
/* Function prototypes */
int acl (char *, int, int, struct acl *);
int aclsort (int, int, struct acl *);
/* Following prototype provided for internal product use only */
int acl_save_restore (char *, int, int, char *);
That should answer your question for defined symbols too.
Your sample program:
$ cat foo.c
extern int acl (char *); int foo (const char *s) { return acl (s); }
$ c89 -c foo.c
extern int acl (char *); int foo (const char *s) { return acl (s); }
^
"/home/jojo/foo.c", line 1: error(252): argument of type "const char *" is
incompatible with parameter of type "char *"
1 error detected in the compilation of "foo.c".
c89: /usr/cmplr/ccombe exited, returning 2.
$
Our compiler treats this as an error rather than a warning.
Enough for today, I'll look into this again tomorrow...
Bye, Jojo

This is an OS on which gnulib was never tested so far. Therefore I have to
start with a few basic questions:
- What is the official name of the OS? NonStop? NonStop OS? NonStop UX?
Also the version number (for reference in gnulib documentation)?
- What is the result of config.guess?
$ sh build-aux/config.guess
- What are the predefined C compiler macros? __TANDEM, what else?
__hpux also?
Then, three questions about the ACL support. First, where is a reference of
the API? I need this info for updating
<http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=doc/acl-resources
.txt>
- Which include files declares functions related to ACLs?
- Which symbols are defined? Something like
$ nm /usr/lib/libc.so | grep acl
should provide the list.

Just a test case: When you try to compile this file with "cc -c foo.c"
======================== foo.c ======================== extern int acl (char
*); int foo (const char *s) { return acl (s); }
=======================================================
what is the result?

gnulib contains a couple of unit tests for this code. sed-4.2.1 doesn't.
Therefore I'd like to ask you to repeat your effort with this tarball:
http://www.haible.de/bruno/gnu/acltestdir.tar.gz
With your changes, does only the compilation pass, or does "make check"
also pass?

Try to only preprocess the file:
$ cc -DHAVE_CONFIG_H -I. -I.. -I../lib -I.. -I../lib -I/usr/local/include
-g -E btowc.c > i.c and look at i.c. Here it should be easier to spot which
tokens before 'struct random_data' are confusing the compiler.
