xserver compilation issue

[timwoj at ieee.org]

I've been trying to build x.org using the build.sh script.  I've managed 
to fix a few things (a few files didn't exist in Mesa and I had to fix the 
link script for that).  But I'm stumped on this one.  xserver builds all 
the way through, then dies during installation with:

xdmxconfig-xdmxconfig.o: In function `dmxConfigReadFile':
/tmp/x11r71/xserver/hw/dmx/config/xdmxconfig.c:402: undefined reference to `yyin'
/tmp/x11r71/xserver/hw/dmx/config/libdmxconfig.a(parser.o): In function `yyparse':
/tmp/x11r71/xserver/hw/dmx/config/parser.c:1582: undefined reference to `yyerror'
/tmp/x11r71/xserver/hw/dmx/config/parser.c:1143: undefined reference to `yylex'
/tmp/x11r71/xserver/hw/dmx/config/parser.c:1593: undefined reference to `yyerror'
/tmp/x11r71/xserver/hw/dmx/config/parser.c:1587: undefined reference to `yyerror'
/tmp/x11r71/xserver/hw/dmx/config/parser.c:1701: undefined reference to `yyerror'

This with yacc/bison 2.1.  Any ideas?
