Do you have figures for 1.6.3 and 1.7.9?  That may help
narrowing the problem.  

Also it would be interesting to describe your tree a bit more (I
presume you cannot publish nor reduce your test case...).  How
many configure.{in,ac} do you have?  Do you use lots of
AM_CONDITIONALS? (How many per-subproject, and how many
per-Makefile.am?)

You could also run automake in `--verbose' mode and try to get
the feeling of were time is spent.
