I think this is a regression against 4.2.2 as I have working compilers for sparc-sun-solaris2.10 and sparc64-sun-solaris2.10 which were both configured with --with-dwarf2 (although I didn't build them myself so I'm not 100% sure)
Comment 3 Eric Botcazou 2008-08-29 20:26:16 UTC 
Remove --with-dwarf2, it is useless now.
Comment 4 Jonathan Wakely 2008-09-01 08:39:04 UTC 
Yes, I realise that, but it's still documented and it was apparently harmless with 4.2.2

It's still documented because it's still useful on platforms that don't default
to DWARF-2, which is not the case of Solaris anymore.
