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

# Power MachTen is a real memory system and its standard malloc
# has been optimized for this. Using this malloc instead of Perl's
# malloc may result in significant memory savings.

# Make symbol table listings les voluminous

# Increase perl's stack size.  Without this, lib/complex.t crashes out.
# Particularly perverse programs may require that perl has an even larger
# stack allocation than that specified here.  (See  man setstackspace )

# Install in /usr/local by default

# 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.

# 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

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.

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.
