Hi!
As discussed on IRC, this patch introduces two new attributes,
so that the C library (and other headers) have a way to
a) tell the compiler something about functions like aligned_alloc
or memalign
b) tell the compiler the alignment of poi

Hi!
As discussed on IRC, this patch introduces two new attributes,
so that the C library (and other headers) have a way to
a) tell the compiler something about functions like aligned_alloc
or memalign
b) tell the compiler the alignment of pointers returned say by malloc
Ok for trunk if bootstr
