The a.out compatibility works flawlessly once I copied all the dynamic 
libraries from /usr/lib and elswhere and I'm now running with the ELF 
tree that I built.

I did have to restore sendmail to an a.out binary as the ELF one repeatedly 
failed to send mail reporting rewrite problems. This occured both with my 
original sendmail.cf and with a new one generated from the same .mc file. 
An a.out sendmail from a couple of weeks ago (which reports as the same 
version) was perfectly happy with both config files. Anyone got any ideas 
what is going on here?
