Dear Vladimir, thanks! I was also about to do this, but I am not sure whether the headers are compatible with the compiled binaries afterwards. After all, my code is used within our group in Linux, Mac and Windows and I don't want to modify GiNaC since I am currently linking against the repository binaries for Linux, the homebrew package for Mac and the compiled binaries for Windows you kindly sent me some time ago. However, in the worst case I will add the modified GiNaC to my code and compile it along with my code on all platforms.

Following the previous discussion I am attaching just in case a trivial patch which opens an access to expairseq elements.
