Download port (v6.7.5) for 32/64-bit Microsoft Windows® built by MingW.
The program `lifeconv.exe' (to convert data) is just a copy of
`xlife.exe'.  Use it without redirection, e.g.,
lifeconv -M patt-in.rle patt-out.l
The Cygwin's version has several
advantages over this port:
 Xlife requires only minimum Cygwin support.  It is easy to install 
Cygwin, compile and use Xlife. To build Xlife for Microsoft Windows with MingW you need to use Xlife sources and 
patched sources of David Kinder's wrapper for Xlife sources.  The compilation 
maybe described in the next steps:
 This process may have variations for the differrent compilers.
