# machten.sh
# This is for MachTen 4.0.2. It might work on other versions too.
#
# MachTen users might need a fixed tr from ftp.tenon.com. This should
# be described in the MachTen release notes.
#
# MachTen 2.x has its own hint file.
#
# This file has been put together by Andy Dougherty
# <doughera@lafcol.lafayette.edu> based on comments from lots of
# folks, especially
# Mark Pease <peasem@primenet.com>
# Martijn Koster <m.koster@webcrawler.com>
# Richard Yeh <rcyeh@cco.caltech.edu>
#
# File::Find's use of link count disabled by Dominic Dunlop 950528
# Perl's use of sigsetjmp etc. disabled by Dominic Dunlop 950521
#
# Comments, questions, and improvements welcome!
#
# MachTen 4.X does support dynamic loading, but perl doesn't
# know how to use it yet.

# Configure doesn't know how to parse the nm output.
usenm=undef
# At least on PowerMac, doubles must be aligned on 8 byte boundaries.
# I don't know if this is true for all MachTen systems, or how to
# determine this automatically.
alignbytes=8
# There appears to be a problem with perl's use of sigsetjmp and
# friends. Use setjmp and friends instead.
d_sigsetjmp='undef'
# MachTen always reports ony two links to directories, even if they
# contain subdirectories. Consequently, we use this variable to stop
# File::Find using the link count to determine whether there are
# subdirectories to be searched. This will generate a harmless message:
# Hmm...You had some extra variables I don't know about...I'll try to keep 'em.
# Propagating recommended variable dont_use_nlink
dont_use_nlink=define
cat <<'EOM' >&4
Tests
io/fs test 4 and
op/stat test 3
may fail since MachTen does not return a useful nlinks field to stat
on directories.
At the end of Configure, you will see a harmless message
Hmm...You had some extra variables I don't know about...I'll try to keep 'em.
Propagating recommended variable dont_use_nlink
Read the File::Find documentation for more information.

# From: Dominic Dunlop <domo@tcp.ip.lu>
# Subject: Re: Perl 5.003 from ftp.tenon.com requires MT 4.0.3
# MachTen 4.0.2 and earlier do not implement System V interprocess
# communication (message queues, semaphores and shered memory); 4.0.3 has a
# half-baked implementation which provides the corresponding library
# functions but does not implement the system calls or provide the header
# files (or documentation). The perl installation process correctly divines
# that System V IPC is not usable in either case. Do not attempt to persuade
# it otherwise, or the resulting perl will crash (rather than producing an
# error message) if you attempt to use the functions.
