'isDefinition' indicates whether or not a specific TagDecl is defining declaration, not whether or not the struct/union/class/enum type is defined.

bool clang::TagDecl::hasNameForLinkage ( ) const

inline

Is this tag type named, either directly or via being defined in a typedef of this type?

C++11 [basic.link]p8: A type is said to have linkage if and only if:

it is a class or enumeration type that is named (or has a name for linkage purposes) and the name has linkage; ... C++11 [dcl.typedef]p9: If the typedef declaration defines an unnamed class (or enum), the first typedef-name declared by the declaration to be that class type (or enum type) is used to denote the class type (or enum type) for linkage purposes only.

C does not have an analogous rule, but the same concept is nonetheless useful in some places.
