Thanks for the quick review Jakub and additional comments from Andreas.

Ah, precisely why I posted it for comments instead of assuming my
patch was somehow "obvious".  Sorry I didn't know about those
releases.  I can see your point and since we are unwilling to discuss
the merits or lack thereof of supporting test releases that were
suppose to be killed upon the release of FSF 2.13 (I do assume that
you and binutils developers know better than I on that point; I don't
want to open that can ;-), I will produce another patch given below.

Since sed commands with multiple -e options are indeed already found
in gcc/configure.in, I will fix the problem using the later
recommendation from Andreas Schwab.

How about this monster instead?  Tested (outside context) to properly
handle all these forms with native GNU sed (Red Hat 7.X) and with
native non-GNU sed (sparc-sun-solaris5.7, i386-unknown-freebsd4.8,
alpha-dec-osf4.0a) (obviously, I invented some version reports):

GNU ld version 2.14
GNU ld version 2.13.2
GNU ld version 2.13.2.1
GNU ld version 2.14 20030513
GNU ld version 2.13.91 20030513
GNU ld version 2.13.91.2 20030513
GNU ld version 2.12.1 [FreeBSD] 2002-07-20
GNU ld version 2.12 [FreeBSD] 2002-07-20
GNU ld version 2.13.2 [FreeBSD] 2002-11-27
GNU ld version 2.13.2.1 [FreeBSD] 2002-11-27

GNU ld version 2.12.90.0.1
GNU ld version 2.12.90.0.1 20030513

Tested in gcc/configure.in context on alpha-unknown-freebsd4.7 where
it fixed the root issue with an FSF binutils version without date report.
