[picking other half of thread]

What about doing the same as for .y and .l files?  Generate them when 
not there, but also bundle generated versions as part of the distro? 
Aat one stage the repository did contain generated lex/yacc files but 
they were removed as they were often out-of-sync and/or badly date-stamped.

(for configure, yes, I agree that it should be generated, it's just to 
big, complicated, and exposed to the local SH version's wim.)
