First, thanks for the response.

This may work but seems like a brute force way of doing it.  Surely,
it can be done with a Red Hat distribution.  Installing another
distribution to cross-compile doesn't sound like a reasonable answer.
Then again, maybe it's just me.  =)

I've scanned the gcc man page and I couldn't find a "--dynamic-linker"
option or anything similar.

I've read the Glibc2-HOWTO and that's where I learned about the
"-nostdinc" and "-nostdlib" options.  It also mentions a "-b" option
but I can't get that to work.  Red Hat 6.0 doesn't appear to have all
of the gcc binaries necessary in the /usr/lib/gcc-lib directory and I
don't know which RPMs to install to get them.  I'd try compiling my
own gcc, ld, and libc5 but that seems to be a chicken and egg problem.

I believe that the "-b" option mentioned in the Glibc2-HOWTO is the
way to go but I need the binaries it points to.  I can't be the only
guy on a Red Hat system that wants to link against libc5.  If there's
not a HOWTO that covers it for Red Hat, help me get it working and
I'll write the HOWTO.  =)
