When I checked it (the right way) in 2.3a, there seems to be no  
difference: they are always relative the /usr/local/share/bison/  
directory in my installation. There, I want a way to make it relative  
the directory 'bison' was invoked.

So this might suffice for that. But what if one writes
  %skeleton "my/lalr.cc"
Would one not expect it to work like
  %skeleton "lalr.cc"
but checking in the subdirectory "my"?

And these seemingly silly little details are used rather intuitively,  
making important to set them correctly. :-)
