* Creating w32 port for compilation of Alpine. This is intended for old

    machines that cannot be updated. Long story short: Always use the
    command "build wnt" to build Alpine. If that does not work, try
    "build w32", which is for machines that are too old and do not have
    any way to use modern encryption protocols such as TLSv1.2.

    The version of Alpine built in modern machines will be called
    alpine.exe, and the binary built with the port w32 will be called
    alpine32 in the repository. All other binaries can be downloaded from
    the main web site, and they will not have the suffix "32" there.
