Ahm.  Duh.  I'm an idiot.  My only defense is that it's after 2am my time.

Yikes!  I /just/ tried this against GLPK 4.45 that I compiled, literally 
5 minutes before sending that email.  I'll try again ...

Wait, I'm talking about the RHS of _constraints_ only.  I know that GLPK 
supports inf and infinity in the Bounds section.  Here, does this help 
explain my error/question?  (It's against the same file I attached in 
the previous message.)
