Not sure what you mean by "appended" here... I see no attachment and my 
mail clarily stated that I could not generate the configure script using 
the autotools.

Well, what I was thinking was to have something telling the user that 
the sources requires version x.y of bison rather than silently breaking 
during the compile stage with some obscure error message.

Yes, this is how I solved it on out system, but it's still not as 
helpful as a configure error would have been to let others know that the 
bison version is too old...
