You appear to have regenerated configure, on both mainline and 4.2 branch, 
with autoconf 2.60.  Could you please regenerate it with 2.59 in both 
places?  2.59, exactly, is the version documented in install.texi.  In 
order to avoid random churn with versions going back and forth and 
different versions in different directories with no good reason, we must 
have a transition plan before changing the version used (and keep 
install.texi up to date throughout the transition with what version is 
used in what directory), and we have no such plan; certainly such changes 
are inappropriate on release branches.  The changes to directory variables 
and new configure options in autoconf 2.60 make such a transition plan 
especially important (for example, we need to work out at what point the 
local configure options --with-datarootdir --with-docdir --with-htmldir 
get removed in each directory in favour of the standard options added in 
2.60).  2.60 also needs automake 1.10 (and vice versa).
