Thanks Ian (and Andreas).
I'm [currently] tying binutils to gcc because its difficult to
determine past binutil version numbers. For example, I believe -relro
and -now originated around 6/2004 from ld/ChangeLog_2004. The log does
not state what the version is/was in effect; there does not appear to
be a Binutils Timeline (similar to http://gcc.gnu.org/releases.html);
and the FTP archives does not list a binutils dated near around
(http://ftp.gnu.org/gnu/binutils/).
Would you (or anyone else) have a suggestion? I seem to have reached
my sluething limit.
