+    gcc: don't clobber stamp-bits with a symlink to itself
+    
+    Several versions of gcc have an issue in libstdc++v3 where the build may
+    clobber stamp-bits with a link to itself.  This doesn't manifest itself
+    on all systems.  On several Ubuntu systems, this doesn't appear to be a
+    problem, but it is an issue on Fedora 16 systems.
+    
+    To fix the issue, we'll simply filter out stamp-bits from the symlinks
+    to be generated.
+    
+    Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
+    there.
