svn commit: samba r25874 - in branches/SAMBA_4_0/source/heimdal_build: .

New Revision: 25874

WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=25874

Log:
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.
