chances are they're using inline asm that gets a deprecated warning with gcc-3.4.4, but people ignore it because it doesnt abort :P find a fix from upstream
Created attachment 69805 [details, diff] Upstream amd64 fixes Here's the fixes I found upstream that seem to fix the build problems.
Make sure you double and triple check these kind of patches. There was one version that caused gcc 3.3 to emit wrong code.
It should be a backport from the cvs, committed after a brief test.
