Mine was 10 1/2:

Does a CG6 work?  With X11R6?  I'm about to do a hardware swap and will use
an IPC with 36 Mb and a GX (present is 24 Mb and a CG3) if it works ...

I suggest applying fix-05 as well.

The good news with fix-05 is that it only alters 2 files that are changed by
the Aussie patches (and thus by my twiddled-for-fix-04 patches).  Those are
sun.h and sunInit.c down in xc/programs/Xserver/hw/sun.

You can apply fix-05 by going down in there to that directory, and move the
NetBSD-ized sun.h and sunInit.c out of the way (i.e., move the Consortium
.orig's back temporarily).  Once you've done that, you can apply fix-05.
You'll then have to go back and re-patch (NetBSD-ize) sun.h and sunInit.c
manually.

If you haven't done this already (i.e., applied the NetBSD patches to an
up-to-fix-04 R6), then you can use the twiddled-for-fix-04 stuff I posted,
with one tiny change:

netbsd4me# diff -rc1 X11R6_NetBSD_sparc_patches.thru_fix-04 X11R6_NetBSD_sparc_patches.thru_fix-05
*** X11R6_NetBSD_sparc_patches.thru_fix-04      Sat Sep  3 20:46:15 1994

i.e., in the very last fix for "sun.h", bump up the line numbers by 2.

Then you can apply the NetBSD patches and be on your way.

I got this too and ignored it.  imake.c declares it "char *"; stdio.h says
"const char *".  #ifdef __NetBSD__ it if you care.

Hmmn, this didn't happen to me ... I wonder if the SharedXmuReqs change to
bsdLib.tmpl, perhaps?  (I didn't make that change when I built it originally)

Sometimes you get this error if you have spaces instead of a tab as the first
whitespace on a dependancy line ...

The other check is more basic - is the Imakefile (or Makefile) mangled?

The top of both Makefiles should just have comments in them:

netbsd4me# head programs/xinit/Makefile
# Makefile generated by imake - do not edit!
# $XConsortium: imake.c,v 1.89 94/08/12 00:45:51 gildea Exp $

Line 5 in both is "# Makefile generated from "Imake.tmpl" and <Imakefile>".

Ah, you got bitten by the "crypt" Secret Hidden File Trick :-)

There's a file hidden in ftp.X.ORG's FTP tree that you can grab iff you're in
the US that you're supposed to install as xc/lib/Xdmcp/Wraphelp.c first.
Read the RELNOTES:

3.4.  Configuration Parameters

...
The file xc/lib/Xdmcp/Wraphelp.c, for XDM-AUTHORIZATION-1, is not included
in this release.  The file is available within the US; for details get
/pub/R6/xdm-auth/README from ftp.x.org via anonymous FTP.

Got these and ignored them.  (-:

Fetch the Wraphelp.c file and rebuild, that'll get you libX11 which will get
you the rest (libXdmcp at least).

I suggest you check the Imakefile and Makefile for spaces vs. tabs, although
it would help if you told us just what *is* on line 5 of your Makefiles ...
