Git

System: Microsoft Windows XP Home Edition
CPUs: Intel(R) Atom(TM) CPU N270 @1.60GHz.
Deps: Git-2.10.0-32-bit.exe

I thought to compile emacs-25.1, and manually installed the gcc-6.1.0-1 and dependency
packages, but when I ran the configure script with CFLAGS and examined the config.log
the CFLAGS had been appended with a duplicate entry for -mtune=. Therefore I do not
recommend using this [the MSYS2] distribution's toolchain on i686; obviously on x86_64
one wouldn't use a CFLAG as -mtune=. The below is written simply to provide the reader
with access to Github, and owing to it's inclusion of shells, Tcl/Tk, and UNIX utlities.

Owing to the newer Git releases' reliance on CancelSynchronousIo
in KERNEL32.dll, Git-2.10.0-32-bit is the last version supporting
MS® XP

https://github.com/git-for-windows/git/releases/tag/v2.10.0.windows.1
Git-2.10.0-32-bit.exe

I opt out of Window Explorer integration and file associations, Use Git from Git Bash
Only, Checkout as-is, commit Unix-style line endings, Use Windows' default console
window, and Enable file system caching. As I don't have .NET framework v4.5.1 on
the computer - XP doesn't support that version - I opt out of using the Git Credential
Manager.

C:\Programmer\Git
458 MB (480.484.174 byte)

The download ships with Perl 5.22.1 and Tcl/Tk 8.6.5.

The .pod files (perldiag.pod, perlfunc.pod, perlop.pod) needed
in Perl scripts for 'use diagnostics;' and for, e.g., the command
'perldoc -f sprintf' are not included; so create a 'pods' directory
in /usr/share/perl5/core_perl and copy them there.

If you want to run tclsh86.exe and/or wish86.exe from Git CMD
modify the %PATH% adding C:\Programmer\Git\mingw32\bin.

C:\DOCUME~1\UserName>TYPE tcl.bat
@ECHO OFF

tcsh-6.18.01.tar.xz

Extact the tcsh-6.18.01 archive above and modify csh.login to read /usr/bin/tcsh,
then copy csh.cshrc and csh.login to both C:\Programmer\Git\etc and to your home
directory, on the latter renaming these, respectively, to .cshrc and .login; bindkey.tcsh
and complete.tcsh should go in \etc\profile.d. Line 40 with the 'goto' statement should
be commented out in .cshrc for the customisations below that line to have any effect.

# afterwards because it's added again (and correctly so) in /etc/csh.login.
set path=( /bin $path:q )

Create a Desktop Shortcut for mintty.exe and modify it as follows:

Destination: C:\Programmer\Git\usr\bin\mintty.exe /usr/bin/tcsh -l

Start i: %HOMEDRIVE%%HOMEPATH%

If instead you want an interactive session change the tcsh argument to '-i'.

NB: In /tcsh-6.18.01/cygwin/csh.cshrc the first 'if' block complains when sourcing MSYS2's
/etc/profile.d/perlbin.csh, so rename that file to perlbin.csh.bak, and in your .login file before
'umask 022' add these lines:

setenv PATH "${PATH}":/usr/bin/vendor_perl:/usr/bin/core_perl

# If you have modules in non-standard directories you can add them here.
# setenv PERLLIB dir1:dir2

Git-2.10.0-32 does not include a .csh equivalent for /etc/profile.d/lang.sh, Martell Malone has one at
https://github.com/martell/MSYS2-Base/blob/master/etc/defaults/etc/profile.d/lang.csh, but I prefer
using a modified (for the PATH) copy of Slackware's.

C:\Programmer\Git\etc>TYPE profile.d\lang.csh
#!/usr/bin/csh
# Set the system locale.  (no, we don't have a menu for this ;-)
# For a list of locales which are supported by this machine, type:
#   locale -a

# en_US is the Slackware default locale:
setenv LANG en_US

# 'C' is the old Slackware (and UNIX) default, which is 127-bit
# ASCII with a charmap setting of ANSI_X3.4-1968.  These days,
# it's better to use en_US or another modern $LANG setting to
# support extended character sets.
#setenv LANG C

# There is also support for UTF-8 locales, but be aware that
# some programs are not yet able to handle UTF-8 and will fail to
# run properly.  In those cases, you can set LANG=C before
# starting them.  Still, I'd avoid UTF unless you actually need it.
#setenv LANG en_US.UTF-8

# Another option for en_US:
#setenv LANG en_US.ISO8859-1

# One side effect of the newer locales is that the sort order
# is no longer according to ASCII values, so the sort order will
# change in many places.  Since this isn't usually expected and
# can break scripts, we'll stick with traditional ASCII sorting.
# If you'd prefer the sort algorithm that goes with your $LANG
# setting, comment this out.
setenv LC_COLLATE C

# End of /etc/profile.d/lang.csh

C:\Programmer\Git\etc>

A (modified) Slackware coreutils-dircolors.csh file.

C:\Programmer\Git\etc>TYPE profile.d\coreutils-dircolors.csh
# Slackware color ls profile script for /bin/csh-like shells.

# Set up LS_OPTIONS environment variable.
# This contains extra command line options to use with ls.
# The default ones are:
#  -F = show '/' for dirs, '*' for executables, etc.
#  -T 0 = don't trust tab spacing when formatting ls output.
#  -b = better support for special characters
setenv OPTIONS "-F -b -T 0"

# COLOR needs one of these arguments:
# 'auto' colorizes output to ttys, but not pipes.
# 'always' adds color characters to all output.
# 'never' shuts colorization off.
setenv COLOR auto

# This section shouldn't require any user adjustment since it is
# simply setting the LS_OPTIONS variable using the information
# already given above:
setenv LS_OPTIONS " $OPTIONS --color=$COLOR "
unsetenv COLOR
unsetenv OPTIONS

# Set up aliases to use color ls by default.  A few additional
# aliases like 'dir', 'vdir', etc, are some ancient artifacts
# from 1992 or so...  possibly they should be disabled, but maybe
# someone out there is actually using them?  :-)
alias ls '/bin/ls $LS_OPTIONS';
alias dir '/bin/ls $LS_OPTIONS --format=vertical';
alias vdir '/bin/ls $LS_OPTIONS --format=long';

# if ($status == 0) then
#   eval `/bin/dircolors -c $HOME/.dir_colors`
# endif

# if ($status == 0) then

NB: Git Bash as I have a Danish MS® system, reads the /profile.d/lang.sh file
when starting, and exports to the shell 'LANG=da_DK.UTF-8'.

Though in certain circumstances there are problems using mintty.exe, as from the
above lang.csh, there are sometimes problems with LANG set to UTF variants.
