See http://sources.redhat.com/ml/binutils/2001-05/msg00435.html
and the followup.

revision 1.35
date: 2001/05/25 01:59:43;  author: amodra;  state: Exp;  lines: +0 -13
Revert last patch.
----------------------------
revision 1.34
date: 2001/05/25 00:01:30;  author: amodra;  state: Exp;  lines: +13 -0
        * expr.c (expr): Set return value to absolute_section for
        subtractive operations on symbols within a segment.
        * read.c (pseudo_set): Set segment for complex expressions.

Looks like I reverted the ChangeLog too.  That was a bit naughty.

With the current assembler, you get a branch to start+2.  Seems OK to me.
