Gee, I think I can see what's wrong:

~/lectures/compilation-lecture-that-has-automake-fail % autoconf --trace AC_INIT
func_success failed.
func_success failed.
Found no shell that has working shell functions.

Please tell address@hidden about your system.
configure.ac:21:AC_INIT:Compilation Lecture:0.1:address@hidden
~/lectures/compilation-lecture-that-has-automake-fail % autoconf --trace 
AC_INIT > /dev/null
~/lectures/compilation-lecture-that-has-automake-fail %          nostromo 11:25

So apparently there is some code in Autoconf that checks for function
support that reports it on STDOUT!  I don't have spare time to spend
on Autoconf, but it would be great if this could be fixed.  Maybe it
is, but I still have not changed my env to use the new CVS procedure
at Savannah :(
