Yoink Win32 Dependencies
Created `date`

These dependencies were generated automatically by makedeps.sh available in
the Yoink repository.  You should find here all the header files, DLL's,
implibs, and pkgconfig files required to build Yoink that are not provided
with the standard mingw32 toolchain.

These files are licensed such that their general distribution under
reasonable conditions is allowable.  The copyrights of these binaries go to
their various respective owners.  Look up the specific library for specific
terms and conditions, or see the COPYING file in the Yoink package.
