Hello,

the submitter's e-mail address is no longer valid (nor is the domain).  
Given that this has been in feedback for over a year, and we certainly  
won't be getting any responses from the original submitter, I vote we  
either suspend this PR, or close it entirely. We do have several  
successful 32bit and 64bit builds on this platform of 3.2, including  
some with binutils in our list of successful builds.
