I have a question about libgcc export for shared libraries... libgcc exports (via libgcc-std.ver): __ffsdi2 but not: __ffssi2 . Is there any particular motivation not to, or should it, or, does it just not matter a whole lot? If people think it would be good to do, I'd be happy to do up a patch for it, but, I don't want to propose it, if it isn't a good idea. :-)
