This is a place holder for Aiksaurus.lib and Aiksaurus.h both are a requirement to build the Thesaurus DLL plugin for Windows To create Aiksaurus.lib you will need MC Visual C++ Version 6.0 or better Check out http://www.aiksaurus.com and get source code for Aiksaurus. Once you get the source code, there is a subdirectory of Aiksaurus - core/src. Inside there is a MakefileLIB.msc. To build a statically linkable Aiksaurus.lib do nmake -f MakefileLIB.msc With the creation of Aiksaurus.lib, copy/move it and Aiksaurus.h to this directory and continue with the AbiWord build process for this plugin.
