section ids

section ids

[Alan Modra]

I've checked in the following patch to make the section sequence ids
non-negative for the standard sections.  There wasn't really anything
wrong with the original scheme, but this way is a little more logical, and
may avoid future surprises (eg. sprintf %x printing lots of digits and
overflowing buffers)
