Sources for dependencies of ezwinports programs

This directory holds source distributions for all the libraries which
I didn't build myself, and which are used by the various ezwinports
programs.

To comply with GPL, the sources for all of those libraries, for
exactly those versions I used to link executables and other DLLs I
built, need to be available from the same place where I put the
binaries.  So here they are.

Each package below is followed by the names of DLLs that correspond to
that source package.
