Someone wants gcc 4.3.2 libraries, but the Cygwin install instructions 
assume you are using gcc 3.4.4.  Is it possible that you have installed 
cppunit 1.12.1 instead of 1.12.0?  You need to be careful: Any updating of 
Cygwin packages will update cppupnit to 1.12.1 unless you specifically tell 
it not to in the "Pending" view of Cygwin setup.

As an aside, it is helpful when reporting problems like this to show a 
little more of the output, including the libtool and g++ commands that 
preceded the error message.
