Then perhaps there should perhaps be a more formal formulation: 
"bison-2a is only supported for use with m4-1.4.3", perhaps with an 
explanation that bison might work with earlier versions of m4, but 
there are no guarantees.

In addition, I think Bison should make some check for version of m4. 
For example, if bison is run, and m4 is old, a warning should perhaps 
be issued. And when people report bugs, there should perhaps be a 
printout of some sort, showing which m4 version was used.
