Thanks for suggesting this. Indeed my PATH has /usr/xpg4/bin in front, but 
config.status is sometimes generated with /bin/bash, and some others with 
/bin/sh (investigating the conditions on that). I've never seen 
/usr/xpg4/bin/sh been chosen.

Where is the source for this shebang generation? Maybe I can make some 
sense out of it.
