Okay, it doesn't.

I have generated two assembly files, x1 and x2, to be the
output of the normal compiler command for xc/lib/X11/x11trans.c
with the -S option added.

The difference is that, before compiling x2, I have patched
xc/lib/xtrans/Xtrans.c with this:
--- Xtrans.c    19 Mar 2005 17:19:31 -0000      1.2
+++ Xtrans.c    16 Apr 2005 22:41:59 -0000

If I do a
$ as -o x11trans.o x1
then rebuild and install libX11.so.6.2, it doesn't work.
If I do a
$ as -o x11trans.o x2
then rebuild and install libX11.so.6.2, it works (and outputs a string).

Then I have diff'd x1 and x2 and reduced the diff (by making
x1 similar to x2), so that it now looks like:

i.e. the only thing from x2 I removed was the actual
function call to fputs. It does not work.

After that, I removed *ONLY* the "call fputs" line from x2,
and it does not work. (???!)

Can anyone help me to dig into this further?

PS: To XFree86 developers: I can give out shell accounts on request;
    it's easier if you have IPv6, but I can manage to do so for IPv4 too.

No, the only way I've seen them sold is for $40 with a free OpenBSD CD.
