Not storage class specifiers in C (const, volatile and restrict are type 
qualifiers, inline is a function specifier).  However, typedef is a 
storage class specifier in C.  And so in C1X is _Thread_local - I imagine 
we'll end up making both __thread and _Thread_local use RID_THREAD and 
having GCC accept all the cases that are valid according to C1X (plus any 
other existing GNU cases unless -pedantic) rather than having distinct 
rules for the two spellings.

Thus, if the definitions of storage class specifiers for C and C++ are 
incompatible I don't think this belongs in c-common.c - or maybe the 
function should be renamed and the comment adjusted to reflect the actual 
rules for the set of keywords included.
