Rather than letting it get even more stale, remove README.MinGW.

-This is a port of GIT to Windows using MinGW.
-
-The goal of this port is to have the tools runnable from the Windows
-command line, not from MinGW's rxvt+bash environment.

-INSTALLATION
-------------
-
-In order to compile this code you need:
-
-- MSYS, e.g. MSYS-1.0.11-2004.04.30-1.exe
-- MinGW, e.g. MinGW-5.0.2.exe
-- mingwruntime, e.g. mingw-runtime-3.9.tar.gz
-- compilers and tools:
-	binutils-2.15.91-20040904-1.tar.gz
-	gcc-core-3.4.2-20040916-1.tar.gz
-	gcc-g++-3.4.2-20040916-1.tar.gz
-	gdb-6.3-2.exe
-	mingw32-make-3.80.0-3.tar.gz
-	unzip-5.51-1-bin.zip (this is not from MinGW, iirc)
-	msysDTK-1.0.1.exe (contains ssh, perl)
-	bash-3.1-MSYS-1.0.11-snapshot.tar.bz2
-- additional libraries:
-	zlib-1.2.3-mingwPORT-1.tar
-	w32api-3.6.tar.gz
-	tcltk-8.4.1-1.exe (for gitk, git-gui)
-	libiconv-1.9.2-1-{lib,bin,lib}.zip (for git-am,
-		from http://gnuwin32.sourceforge.net/packages/libiconv.htm)
-
-I am using these settings in config.mak to have pointers to the right tools:
-
-TCL_PATH=tclsh84
-TCLTK_PATH=wish84
-SHELL_PATH=D:/MSYS/1.0/bin/sh
-PERL_PATH=D:/MSYS/1.0/bin/perl

-STATUS
-------
-
-This code base will not compile on a POSIX system, although any help
-to introduce the necessary #ifdefs is welcome.  As such the status quo
-is in no way intended to be merged upstream.
-
-This works:
-
-- All the plumbings.
-- Many porcelains, in particular, checkout, add, rm, commit, diff,
-  branch, merge, rebase, log, show, bisect, grep...
-- pull, clone, fetch, push via native git protocal as well as ssh.
-- Local pull, clone, fetch, push.
-- gitk, if invoked as "wish84 <prefix>\bin\gitk". Ditto for git-gui.
-
-This does not work:
-
-- daemon, svn, *import, cvs*
-- and certainly a lot more that I never have found a need to look at.
-
-Caveats (aka bugs):
-
-- Internally, the ported tools must do their own command line quoting
-  when other plumbings are executed. This sort of quoting is currently
-  implemented *very* simplistic: It just watches out for whitespace
-  and double quote `"' characters. This may become a problem if you have
-  exotic characters in your file names.
-
-- It seems that MSYS's default bash, 2.05b, has a bug that breaks git-am
-  (and, hence, git-rebase).  If you see this error:
-
-	Patch is empty.  Was is split wrong?
-
-  you need bash 3.1: Just unpack bash-3.1*.tar.bz2 and copy its bash.exe
-  over $MSYS/bin/sh.exe.
