This is the example from chapter 25 of the Goat Book. I typed it by hand first. When
it didn't work, I downloaded the example files to a clean directory & tried again.
It works in static mode ("./configure --disable-shared"), but not in dynamic mode.
I'm running the following versions:
Cygwin - 1.3.1
Automake - 1.4
Libtool - 1.4
Autoconf - 2.13
Make - 3.79.1
gcc - 2.95.3-4 (cygwin special)
