            Bug ID: 67318
           Summary: [6 regression] Parsing error when using abbreviated
                    integral type names in template parameter pack
                    declaration
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: adrian.wielgosik at gmail dot com
  Target Milestone: ---

The following code:

template<short...>
struct MyStruct;

int main(){}

Results in an error:

main.cpp:16:15: error: expected ‘>’ before ‘...’ token
 template<short...>
               ^

Happens for: short, long, long long, unsigned, signed, unsigned short...
Does not happen for: all the above with "int" appended, int, char, bool.
