From what I can assertain, the Dev-C++ principle gets around this by generating the version information as discussed in the link from my previouis post, and then appends this data into an .rc file with a file entry projectname_private.rc. It then includes your normal resource.rc file before passing the new file to the resource compiler. This behaviour may also work for your plugin. It will also save having to modify the existing project resource file before compiling.
