I did a 'git pull' then configure + make just to be sure I'm up to date.  Errors 
still occur.  Hmm.  I suppose it's some local issue then.

I read the error msgs as double defs of imports in w32api/libadvapi32.a vs 
libcygwin.a.  I don't understand why the linker cares.  Is it that there are no 
defs of the corresponding Lsa* functions among the linker inputs?  I'll dig on.
Thanks,
