I was referring to the "how you configured the build" part. These two variables tell exactly how configure.bat was invoked. > This lets me know that he used a MinGW32 toolchain.

Well, I just told you about it, didn't I? ;-) So now you know. Also, it's mentioned in nt/INSTALL. > The values in dynamic-library-alist (formerly image-library-alist) don't > give any indication of what the build actually supports.

Everything in dynamic-library-alist is supposed to work; if something doesn't, please submit a bug report. > All of this information is also useful for anybody trying to build emacs > themselves, to understand whether they have the right versions of > libraries. The information for that is in nt/INSTALL; again, if something is missing or unclear, please tell the specifics.
