>How much of this "breakage" is truth and how much FUD?

I ran "make configure" on all 220 ports with USE_AUTOCONF or USE_AUTOMAKE
using autoconf 2.52, 2.13-000227 (today's autoconf port) and 2.13 (last
week's autoconf port).

I used NO_DEPENDS, so the data is somewhat noisy, however the baseline
with 2.13 helps to put an upper bound on the noise.

The raw data:

2.52 failure rate: 81 + 45 / 220
2.13-000227 failure rate: 14 + 74 / 220
2.13 baseline failure rate: 14 + 74 / 220

These are "autoconf failures" + "./configure failures" / "total ports".

At best, there are 38 ports (81+45 - (14+74)), 17% that fail with autoconf
2.52 .  At worst, there are 67 (81 - 14), 30%.

I think the docs overstate 2.52's backwards compatability.

A port-by-port list is at http://people.freebsd.org/~fenner/autoconf.txt .
The output of the 2.52 and 2.13 runs are
http://people.freebsd.org/~fenner/autoconfcheck-2.{52,13}.txt .  The
output of the 2.13-000227 run is different from the 2.13 run in
unimportant ways, but I guess I could publish that too if anyone cared.
