redefinition of constant/macro (symbol "GLOBAL_TAG_TYPES")

[Vince0789]

This seems to occur when y_hooks is used. It includes y_globaltags somewhere which defines this constant but then indirection attempts to define it again.

This issue doesn't appear by the way when using the files from the releases page of the YSI library.

EDIT: It is caused by not using the latest version of both YSI and indirection.
