There's a spirited discussion about that very topic underway on the  
bug-gnulib list.  The issue is still unresolved.

In the meantime,  I would suggest adding some verbiage to the INSTALL  
file.  (While we're at it, it might be good to figure out how to build  
a fat binary.  I've never done it before so I don't have a clue.  Do  
you have to build the whole thing twice?  Is there a -m32/64 flag?)
