I to have run into the same problem.  

Interesting fact: I was able to successfully build and install Gnu Mailutils last year,
July 2009.  It contained then most of the example <source>.cc files that will now, (sometime in 2010) compile, but it did then.  

This indicates that it just be a libtool or other make chain related tools that doesn't quite cut the mustard, with regards to C++ progamming language source code.

Has anyone else had trouble with makeing C++ programs with cygwin's program building chain of tools?  

Regards
