# Script to port a clean TCL 7.3 or 7.4 distribution to DOS and Windows,
# 16 and 32-bit, ready to compile.
#
# If you have Microsoft C 8.0 or greater (for 16-bit) or MSVC++ 2.2 or
# greater (for 32-bit), TCL will build completely from the ported src code
# generated by this script.
#
# 16-bit should build successfully under MSC 7.0 as well, but this hasn't been
# tested.  32-bit should build under VC++ 2.0 and 2.1, but this also has not
# been tested.  Your mileage may vary with earlier versions, or with another
# vendor's compilor.  I don't have access to anything but MS compilors, so
# if you want to compile it with Borland, you're on your own.
#
# This script is provided "as is" - no copyrights, liabilities,
# or implied warranties are assumed for this script, or the resulting
# compiled src code.  Feel free to modify this script to suit your
# needs, but please respect and preserve the copyrights of UCB,
# Sun Microsystems, and all other parties that have contributed to
# the core TCL distribution, in any and all src code generated by this
# script, whether or not you modify it further.
#
#
# Usage: tcl2dos <src directory> <destination directory>
#
#	where:	<src directory> is the absolute path to an existing, clean
#		TCL distribution.
#
#		<destination directory> is the absolute path to a directory
#		where you want the ported distribution to be installed.
#		If this doesn't already exist, it is created.
#
# You need a way to achieve PC-to-Unix connectivity in order to access
# the destination directory from your PC.
#
# Before running TCL, set the HOME environment variable to the path
# where your home directory is mounted, say "H:\", or if your PC is
# not networked, just use "C:\".
#
# This DOS & Windows port supports DOS style path syntax - backslashes instead
# of slashes.  Unfortunately, this means that you have to use double
# backslashes, so that the TCL interpreter can escape the 1st to get
# the 2nd (for example, C:\\TCL\\LIBRARY).
#
# If the script completes without errors, you can go to the drive and
# directory on your PC in which you installed the ported src and type
# `nmake'.  The makefile will compile the code twice, once for DOS and
# once for Windows.  The DOS binaries will be in the `dos' subdirectory,
# the Windows binaries will be in the `win' subdirectory.  The contents
# of each subdirectory is essentially identical, except for a couple
# of files built specifically for Windows.  The `install' makefile target
# will copy tclsh.exe and libtcl.lib from the `dos' subdirectory to the
# target install directory.  It will also copy tclsh.exe and libtcl.lib
# from the `win' subdirectory to the target install directory as tclshw.exe
# and libtclw.lib, respectively.
#
# Before running `nmake', set the ARCH macro at the top of the makefile
# to the desired target platform for which you want to build TCL.  This
# would be WIN16 for Windows 3.x, and WIN32 (or comment out the line) for
# Windows 95 or Windows NT.

#
# History:
#
#	12/10/95 - add support for 32-bit DOS/Windows
#	10/25/95 - add support for porting TCL 7.4.
#
#		Added static function tmpnam(), written in terms of
#		tempnam(), so tmp files used for implementing pipes
#		can be configured on host machine, rather than based
#		on build machine.
#
#	1/9/95  - change occurrences of "1<<30" to INT_MAX.  Fixes
#		a problem with the 'read' command where failing to
#		supply the number of bytes to read would cause read to
#		fail, and a problem with lreplace where the 'end'
#		keyword was handled incorrectly.
#
#		Convert instances of "/" to "\\", and "//" to "\\\\",
#		so 'glob' and 'file dirname' work correctly.
#
#		Add support for "chdrive" command.
#
#	11/8/94 - Windows build uses LARGE model instead of MEDIUM,
#		fixes memory errors and GPFs with large scripts.
