[Mingw-users] Trying to use 256 colors in Vim

[Maximus <Con...@gm...>]

Hi, it's me again.
I wonder, why MinGW's version of Vim can't switch to xterm-256 color mode?
All OK with "official" Vim.exe (from GVim 73.46) and GIT's vim,
but MinGW's vim just ignores xterm and always works with "win32" terminal.

What I have configured: Latest ConEmu (build 130120), added following lines
to config file C:\MinGW\msys\1.0\share\vim\vimrc

set term=xterm
set t_Co=256
let &t_AB="\e[48;5;%dm"
let &t_AF="\e[38;5;%dm"
syntax on
colorscheme zenburn

But it fails. "echomsg &t_Co &term" prints "256 xterm", but vim
still uses Win32 console API instead of using escape sequences.

What is wrong? MinGW version of Vim is compiled with some restrictions?
