X2) it builds a config.h file for inclusion in C programs.  You may edit

X
XIf you make a mistake on a question, there is no easy way to back up to it
Xcurrently.  The easiest thing to do is to edit config.sh and rerun all the
XSH files.  Configure will offer to let you do this before it runs the SH files.
