r25874: force specific versions for LEX and YACC.
We often have problems with old yacc and bison versions and it seem the combination of LAX and YACC also matters. So we now list all supported version combinations explicit. flex-2.5.33:bison-2.3 only for now. metze (This used to be commit ad0556cbf7c1b0dfc3180a010f2a14d9597c3222)
