Scheme 48 version 0.45 available


Scheme 48 version 0.45 is available as

  ftp://ftp.nj.nec.com/pub/kelsey/scheme48-0.45.tgz

This is an alpha release.  There are likely to be problems, especially with
portability.  Please report bugs to scheme-48-bugs <at> martigny.ai.mit.edu, and
include the version number in your message.

The main difference between 0.45 and 0.36, the last version that was
widely distributed, are:

  - The thread system now uses a version of engines.
  - Threads are built into the usual image.
  - The OS interface has been rewritten.
  - 0.45 includes the source code for the Pre-Scheme-to-C compiler.
    (A word of warning: the compiler is tempermental and buggy and
     is definitely not up to the quality of the rest of Scheme 48.)

Please read the file doc/news.txt for other differences.

                                    -Richard Kelsey

compilation error in s48-0.45 on NetBSD/i386 1.2BETA

c/sysdep.h includes c/fake/sys-select.h, which includes <sys/select.h>
if HAVE_SYS_SELECT_H is defined.

On NetBSD, you need to include <sys/types.h> before you can include
<sys/select.h>.

c/unix/socket.c does not include any header which drags in sys/types.h
before including sysdep.h

The enclosed change allows the file to compile.

Note that on NetBSD, <sys/select.h> doesn't contain any definitions
useful to user-space code; it would probably be better to avoid
including it.

Wow, that seems like bad practice to me.

On AIX, it does, unfortunately.  Is there anything harmful in it?

Tradition.  Flames to /dev/null.

On many/most UNIX systems I've ever used, I've needed to include
<sys/types.h> before including *any* of the kernel-interface include
files (<sys/*.h>)

In that case, it's my fault --- I asked Richard to put <sys/select.h>
in there for AIX portability.  I guess c/fake/sys-select.h should have
an #include <sys/types.h> then, possibly conditionalized on the
existence of <sys/types.h> in configure.in.

Yes, that is the fix that I put in.

It built fine (except for the sys/types.h problem for sys/select.h) on
FreeBSD 2.1.5.

Yes, it built fine on an HP/Apollo 700 as well, once I gave up on HP's
C compiler and used gcc.  (Some problem with fixed or limited table
sizes in the compiler.)

make check failure on 0.44

I am running into an error during make check while installing kali-0.44.  The
error mesage:

<prior messages removed>

Am I missing something obvious?  Any help would be appreciated.  This error
message appears after compiling with gcc version 2.6.3 on a sunos 4.1.3 box, 
2.7.2 on a irix5.3 box, and gcc 2.7.2 on a hpux10.01.
