It is possible to keep native-Windows and Cygwin versions of Vim on a same machine with common runtime files (I have done it; but see Run native-Windows Vim from cygwin without a wrapper for an alternative solution). Here is what you need to do for that:
1. Install the full Windows distribution in C:\Program Files\vim\vim## where ## is the version (e.g. 63 for Vim 6.3, or 70aa for Vim 7.00aa ALPHA).
2. Install the cygwin executables (of the same version and sub-version; the patchlevel may be different), in /bin; don't install the "cygwin runtime files".
Repeat either step 1 or step 2 at each upgrade.
3. Set VIM (in the Windows environment) to C:\Program Files\vim and HOME to your home directory
4. In the cygwin startup files (e.g. ~/.bash_profile) add the following lines:
export VIM=`cygpath -u $VIM` export HOME=`cygpath -u $HOME`
5. All runtime files must be in Unix format. If they aren't, do the following in vim (version 7 or later) for native-Windows (it takes some time but it's fairly automatic). (On version 6 it's possible but since ** wildcards are not recognised it is more work.) (See also Installing several releases in parallel, even with matchit about how to install several _different_ versions in parallel.)
:set nomore :args $VIM/**/*.vim :argdo setl ff=unix :args $VIM/**/*.txt :argdo setl modifiable noro ff=unix :set more
6. Directories $HOME/vimfiles and $HOME/.vim must be made identical. This can be done in Cygwin bash with the following command:
cd ~ ln -s vimfiles .vim
Steps 3 to 6 need be done only once, they remain valid even if you later install a different version.
Note: Cygwin is a "Unix-like" OS, Windows is a "Dos-like" OS. With the above tip, you will use a common _vimrc (and common user plugins) for both. Any differences can be resolved by using
if has("unix") " cygwin-specific code else " native-windows-specific code endif
or even (e.g. if, in addition to this, you use dual-boot)
if has("unix") " code common to Cygwin and Linux if has("win32unix") " code for Cygwin but not Linux else " code for Linux but not Cygwin endif elseif has("win32") " code for windows-native Vim else echoerr "Unknown OS" endif
