libXCBReply.so on Xorg always got errors but the problem was not there.

[supat at supat.eu.org]

I alway got below error:

gcc -Wall -O2 -o .libs/test_reply test_reply-test_reply.o  -L/opt/xorg/lib 
./.libs/libXCBReply.so
/opt/xorg/lib/libXCB.so /opt/xorg/lib/libXau.so /opt/xorg/lib/libXdmcp.so 
-lpthread

I try to compile under exactly fedora build81 condition and also got 
exactly above errors. So, I think error was in xcb/reply program.

But after I get rid off compile errors messages I still cannot press 
cntl-alt-f1-7 to change to console.

I just find the origin of problem today that the problem is on xkb not 
xcb. And I wonder why build 81 can compile in w/o need xcb. I try to get 
rid off using xcb but if move it out then x11 cannot be compiled. Old xorg 
do not have XCBlib in its /opt/xorg/lib at all.
