Only needed for building GRASS, http://download.osgeo.org/osgeo4w/x86/release/mingw (32bit) or http://download.osgeo.org/osgeo4w/x86_64/release/mingw (64bit) 

1. Download [http://sourceforge.net/projects/mingw-w64/files/latest/download latest MinGW-W64 installer].

2. Choose platform `i386` or `x86_64`.

9. Remove `C:\MinGW\bin\libintl-8.dll` (`mingw` package only)

=== Add etc scripts ===

 1. Create `C:\MinGW\etc\ini` and save `msys.bat` into this directory

{{{
PATH %PATH%;%OSGEO4W_ROOT%\apps\msys\bin
if not defined HOME set HOME=%USERPROFILE%
}}}

 2. Create `C:\MinGW\etc\postinstall` and save `msys.bat` into this directory
