Make sure that it works on your machine (there is for instance an article about generating blockMeshes with m4 on the Wiki). Maybe someone with more knowledge about m4 could have an ide what is wrong

That seems to be an issue of the non-system bison 2.4.1 which does not work with the system m4. I tried the system bison 2.1 and now I get:

I'm not sure whether bison 2.1 is still sufficient (like it is stated on the Wiki). The problem is that some version changes in bison modify its C++ support in very subtle ways (I think I saw this problem once. Something with a namespace but I can't reproduce it as my "oldest" bison is 2.3)
