How do you portably pass a jmpbuf as a parameter to a C function?

Some machines define a jmpbuf to be struct { stuff } , while
others define a jmpbuf to be an array.  In one case, an & is required, 
while in the other case it is not.

My best solution was to define my own structure with one field of a 
jmpbuf and then always take the address.

Is there a better way?
