Incompatible type warning - from typedef name to struct name

[Norm Bullen]

It is my understanding that a typedef name is simply an alias for an existing type, whether the type is native or declared by the user. Why do I get a warning '=': incompatible types - from 'DIRECTORY_DATA *' to 'DirectoryData *' when I write an assignment from a variable declared as DirectoryData* to another variable declared as DIRECTORY_DATA*?

typedef struct DirectoryData {

DirectoryData* pNext;

DirectoryData* pPrev;

} DIRECTORY_DATA;

struct {

DIRECTORY_DATA* pFirst;

DIRECTORY_DATA* pLast;

} list;

DIRECTORY_DATA* pRecord;

pRecord->pNext = list.pFirst; // warning '=': incompatible types - from 'DIRECTORY_DATA *' to 'DirectoryData *'

If DIRECTORY_DATA is simply a synonym for "struct DirectoryData" why do I get the above warning?

I realize that I can get around the problem by changing the declaration of "list" or (probably) by using "alias" instead of "typedef".

Thanks

I just realized that my actual code has the keyword "struct" preceding pFirst and pLast in the declaration of list. Correcting the code to make it as above solves the problem.
