Hi Rocco,

You wouldn't be telling this to users, but to developers. Only those  
checking out from Mercurial will need to run autoconf.

End users get the configure script packaged in the tarball whenever a  
developer types "make dist" or "make distcheck".

For developers, we can bump AC_PREREQ([2.54]) to AC_PREREQ([2.60]) so that  
older autoconf versions refuse operation. That would make sure that all  
"make dist" tarballs support --docdir from that point in time forward.

The borderline question is: when will you consider someone building from  
the Mercurial repo a "user" and when a "developer"? I'm inclined to call  
people who check out from Mercurial "developers" - and those can also be  
required to have autoconf 2.60. It's not that new (over three years now)  
so I'd say most distributions would have picked up 2.60 or a newer version.
