Thanks; I didn't know this.

I agree with everything Mike said. Put the comment before the
#define, and lose the "[jsun]". If someone wants to know who wrote
the comment they can use "git blame" and get your full email address.
Actually I'd go a bit further: I think it's be tidier to put the
comment and #define in their own block, separated by a blank line from
the other #defines.
I don't see how GCC can make the GOT smaller with relocs pointing
_after_ the end of the BSS (middle yes, but after?), but given that it
does, the patch looks good to me.
