What was the error message?

Have you tried building it with g++ 4.8.2 under Ubuntu 12.04?
There are PPAs for it
(http://ubuntuhandbook.org/index.php/2013/08/install-gcc-4-8-via-ppa-in-ubuntu-12-04-13-04/,
http://askubuntu.com/questions/271388/how-to-install-gcc-4-8-in-ubuntu-12-04-from-the-terminal)
or you could build a gcc 4.8.2 from source.

There's a possibility that g++4.8.2 is stricter than g++4.6.4 and your
code won't build with g++4.8.2 on any platform, in which case the
Right Thing (tm) is to correct the errors in your project.

I'm typing this on an Ubuntu LTS 12.04 so I can't check what the
previous version of GCC is on Cygwin, but it's probably some other
4.8.x so choosing "previous" in Cygwin's setup.exe probably won't
help.

Your options include building a GCC 4.6.4 from source or the Cygwin
Time Machine ( http://www.fruitbat.org/Cygwin/ )

HTH,
