what I meant there was : since PIC is supposed to eat one register, do
we really have 7 registrers when compiling with PIC ?
I dont think I understand what this patch was fixing and how, so I
cannot help much more.
But previously there was no compile problem and it was under a !(PIC
&& __GNUC__) guard.
