Hi,

While porting DMD's 2.003 source code to Java I realized that in parse.c 
a new method "parseType" with several overloads was added. However, the 
only definition of it is the following:

Type *Parser::parseType(Identifier **pident, TemplateParameters **tpl);

However, in the source code there are several invocations like this:
- parseType(&ai)
- parseType()

This definitely doesn't compile, unless there is some "implicit 
argument" feature in C++ I don't know.

This is blocking my current effort to bring D2 functionality into Descent.

Regards,
Ary

That's incorrect. In parse.h, the correct definition gives =NULL as the 
default value for each parameter.

Thanks! I didn't know you could assign default parameters in the 
declaration and not repeat them in the definition.

Indeed, repeating them would be an error in C++ (though a later
declaration can add additional default argument values).
