Thanks for the suggestion.  It probably would be more convenient, but
changing the autoconf defaults tends to cause unexpected problems so I
prefer to stick with them.  

I'll add a note in the INSTALL file to make the -fexceptions option
more prominent.  Presumably most distributions should be adding this
anyway.
