Daniel's patch keeps the current data structure, which uses 1 bit to indicate whether the function is prototyped or not. I prefer to use 2 bits: TYPE_PROTO_KNOWN and TYPE_PROTO_YES. That allows for three states: known=0 gdb does not know if function is prototyped known=1, yes=0 function is definitely not prototyped known=1, yes=1 function is definitely prototyped I have written such a 2-bit patch.
To be pedantic :-) That's an enum with three states: prototype unknown prototyped unprototyped It can be packed into two bits. enjoy, Andrew
