Well, to avoid earlier reported problems with libc, I installed the freshly
compile libc as version 13.0, and went on to compile some things. A couple
of compile went by without problems, but with rcs this happened:

===> lib
===> ci
cc   -o ci ci.o /usr/src/gnu/usr.bin/rcs/lib/obj/librcs.a -lgnumalloc
ld: ci.o: RRS text relocation at 0x20c5 for "__warn"

Stop.

Stop.

I think something like this was reported before, and Paul Kranenburg said
that it should not happen anymore with a -current linker. However,
my linker (and ld.so) is the result of a 'make cleandir all install' from
yesterday night (before I did the libc compile).

P.S. Hey, the version numbers of libraries don't need to be bumped.. just
     have all binaries to boot the system, and compile & install programs
     around as static binaries, and recompile every other program in
     sight as soon as the library changes 8-)
