Ah, good to know. So the problem I was seeing was separate, and I seem to be
able to resolve it with this change:

Stephen, were you seeing messages like the following when you tested the
corresponding change? What version(s) of autoconf did you test it with?  

Extracting information from the machine- and system-dependent headers...
./configure: line 10356: syntax error near unexpected token `;;'
./configure: line 10356: `      xemacs_cc_cc_mismatch=yes ;;'
