Compatibility? Ha! Let's just say this. G++ 1.35.0 (if Michael T. ever actually makes it "official") will contain many, perhaps even most of the features of cfront 2.0 including multiple inheritance and other recent goodies. To say that G++ was, is, or will be "compatible" with any version of cfront is highly misleading however. I for one have detected a large number of little quirky ways in which G++ differs from cfront, and I hope one day to have *all* of these documented (unless Michael documents them first). In many cases we are talking about little GNU extensions which let you do things that cfront will not let you do, but in some cases, we are talking about GNU-specific restrictions also (such as the ever-present problem with complicated type specifiers, which Michael claims are *not* LALR(1)...but which could be properly handled anyway). Compatibility is only an issue if you are porting code. If you are, I hope for your sake that you are *not* porting anything big (i.e. over 1000 lines) between cfront and G++. -- // Ron Guilmette - MCC - Experimental Systems Kit Project // 3500 West Balcones Center Drive, Austin, TX 78759 - (512)338-3740 // ARPA: rfg@mcc.com // UUCP: {rutgers,uunet,gatech,ames,pyramid}!cs.utexas.edu!pp!rfg
