Thanks. That's probably close enough for me to be able to figure out
what I need.   Since I want to be in the langtools repo, I presume I more
likely need something like
     sh /home/jon/somewhere-else/common/autoconf/configure 
--with-override-langtools=$(pwd)



Aaaargh.   It would seem that "make clean" will delete source files.   
Can I respectfully suggest that "make clean" should check if there is a 
.hg directory, and/or that configure should warn if being executed in a 
source-controlled directory, such as langtools.    Luckily it was a toy 
repo!
