‘xref_tag’ lacks a public declaration

[Ludovic Courtès]

Hello,

‘c-common.h’ lacks this declaration:

  extern tree xref_tag (enum tree_code code, tree name);

AFAICS it makes it impossible for plug-ins to lookup a struct/union/enum
tag.

Unfortunately, <cp/cp-tree.h> declares a different ‘xref_tag’ function,
so it seems that the above declaration cannot just be added to
‘c-common.h’.

Any ideas how to solve this?

Thanks,
Ludo’.
