I think that the state of the matter (of the most recent Bison  
versions), is that you can freely use the C-parser in a commercial  
application, the same way that you can use GCC libraries and the  
like. Check the notice in the parser sources that Bison writes. The  
copyrighting of this parser only applies to the parts that derives  
from the skeleton file. The other parts deriving from the grammar you  
write is copyrighted to you. As for the GLR and C++ parsers, they may  
have different copyrighting notices, but may be synced in the future  
as to become what the C-parser has today.
