Who built these binaries ?  In particular, did you use the binaries that
we built ? (you can find those on unix.secs.oakland.edu)  If you are using
our binaries, you will be able to do

	# grep rel= /etc/perms/gnuc
	#rel=1.37.1d

Also, please cc: all XENIX-related gcc mail to steve@robobar.co.uk.  Thank you.

We don't use gnu-ld under XENIX.

Well, we have Dev Sys 2.3.1 here at RoboBar, but 2.3.4 OS has not arrived yet.

Should be Slibc.a, for Xenix.  Is that a typo?

Odd.  Very odd.  About the only other thing I can suggest is to try using
the /bin/ld from your development system, rather than the operating system:

	(Insert Diskette D01)
	cd / ; mv /bin/ld /bin/ld.save ; tar xf /dev/install ./bin/ld

For certain, the exact same gcc binary works here.  This is the log of
information we need to proceed further:

# cat hello.c
#include <stdio.h>
main()
{
	printf("Hello world\n");
}
# grep rel= /etc/perms/soft /etc/perms/gnuc
/etc/perms/soft:#rel=2.3.1b
/etc/perms/gnuc:#rel=1.37.1d
# what /bin/ld
/bin/ld
