Ah, I see. I guess it is a trivial thing to fix. I am not sure if it
is really important though. Support for the pass through of -R does
not appear to be documented and there is an official way of passing
switches to the linker that does work. Not my call really. The patch
below might make the i386 Linux target consistent with the Sparc
Solaris target, although there are still plenty of other targets that
do not support this abbreviation.
Cheers
