Re: Autogen in Emacs Shell

[Alexander Shukaev]

So I found out that the "/etc/post-install/05-home-dir.post" script changes
to `HOME' depending on `CHERE_INVOKING' (sick stuff I must say).  Setting

  (setenv "CHERE_INVOKING" "1")

solves the problem with unintentional change to `HOME' when "--login" is
present.  Now I can finally invoke 'bash' with

  (defun bash
      (&optional buffer)
    (interactive)
    (let ((explicit-shell-file-name "bash")
          (explicit-bash-args '("--noediting" "-l" "-i")))
      (setq buffer (my-call shell buffer)))
    (with-current-buffer buffer
      (when (equal (buffer-name) "*shell*")
        (rename-buffer "*bash*" t))))

So far so good.  Now onto the original problem since even with "-l" those
issues with 'bsdtar' and inability to find 'automake' by 'autogen.sh' still
remain.  I'm currently looking at the diff between the two `set' commands
from ConEmu and Emacs.  There are of course quite some differences, I don't
want to post all of them not to overwhelm you.  But here are probably the
most interesting ones:

ConEmu:

LANG=en_US.UTF-8
PKG_CONFIG_PATH=
PROMPT=
SESSIONNAME=
SHELL=/usr/bin/bash

Emacs:

LANG=ENU
PKG_CONFIG_PATH='C:\Tools\x64\MSYS2\mingw64\lib\pkgconfig;'
PROMPT='$P$G'
SESSIONNAME=Console
SHELL=C:/Tools/x64/MSYS2/mingw64/libexec/emacs/25.0.50/x86_64-w64-mingw32/cmdproxy.exe

What do you think guys?
