# machten.sh
# This is for MachTen 4.0.3.  It might work on other versions and variants too.
#
# Users of earlier MachTen versions 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

# MachTen 4.X does support dynamic loading, but perl doesn't
# know how to use it yet.

# has been optimized for this. Using this malloc instead of Perl's
# malloc may result in significant memory savings.

# While link counts on MachTen 4.1's fast file systems work correctly,
# on Macintosh Heirarchical File Systems, (and on HFS+)
# 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

During Configure, you may see the message

*** WHOA THERE!!! ***
    The recommended value for $d_semctl on this machine was "undef"!
    Keep the recommended value? [y]

Select the default answer: semctl() is buggy, and perl should be built
without it.

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 nmopts
Read the File::Find documentation for more information about dont_use_nlink

Tests
	io/fs test 4  and
	op/stat test 3
may fail since MachTen may not return a useful nlinks field to stat
on directories.
