[Moved to DR at the September, 2013 meeting.]

Proposed resolution (April, 2013):
Whenthread_local is applied to a variable of block scopethestorage-class-specifierstatic is implied ifitdoes not appear explicitlyno otherstorage-class-specifier appears in thedecl-specifier-seq.

According to 9.2.2 [dcl.stc] paragraph 4,
Whenthread_local is applied to a variable of blockscope thestorage-class-specifierstatic isimplied if it does not appear explicitly.
This, presumably unintentionally, prohibits a declaration like
void f() { extern thread_local int n; }
