Hi, I have applied your patches, modulo I used the flags-based detection 
instead of the type-based one.  I've pushed out a new klibc 0.162 but I 
haven't really had a chance to test out the changes (unfortunately I 
have to run off this morning), so if you guys could verify that it works 
I'll either fix it or move it to Stable.
