Well, temporarily resolved, though not actually solved.  First, it took  
me two tries to realize that the g_network functions are in glib, not  
gtk, but I  got it recompiled with debug info.  Tracing through from  
balsa_window_init, I got totally lost in all the g_ functions, but at  
one point noticed (displaying local variables in the debugger) that  
there had been a g_network_changed  signal, and the network now showed  
as available, and I successfully downloaded my approx 120 queued  
messages.  Unless something in compiling with -ggdb also changed  
something else, and I can figure what it was, I might have to chalk  
this up to "phase of the moon and blue magic dust."
