Here are the results of my testing:
someconditionals/:
automake-1.5: 249.480u 2.660s 4:42.35 89.3% 0+0k 0+0io 341pf+0w
automake-1.6.3: 341.810u 2.840s 6:07.24 93.8% 0+0k 0+0io 356pf+0w
moreconditionals/:
automake-1.5: 1134.130u 6.730s 21:27.70 88.5% 0+0k 0+0io 615pf+0w
automake-1.6.3: 1199.000u 5.520s 21:45.32 92.2% 0+0k 0+0io 578pf+0w
"someconditionals" uses 24 conditionals and has 632 Makefile.am's.
"moreconditionals" uses 24 conditionals and has 635 Makefile.am's.
It sure looks like I ran these on the same machine, and I doubt the
difference is due to 3 more Makefile.am's...
