Well it doesn't. So what is -march=i386 -mcpu=i686 doing in the
CFLAGS?

Sounds like you are using a 386-compiled R in compatibility mode and
are getting bitten by the fact that your gcc is not a cross compiler.
Did you use Martyn's RPMs? If so, I'd try a local rebuild (look up the
docs for rpmbuild) of R from the SRPM.

Another option might be that you need to set up a 32 bit build
environment. I don't know FC3 but on SuSE you have the linux32 prefix
to configure &c.
