No, actually, looking closer at this, the file should be created during 
compilation, but isn't.

If you run bison -d v.mapcalc.y in the directory the file is created and 
compilation works. So it needs some Makefile magic to provoke the 
creation of the file before the compilation of the rest.

The following patch seems to do the trick, but I'm not familiar enough 
with make to judge whether this is the right solution:
