/* Test for valid and invalid combinations of type specifiers.
   This test covers combinations of the reserved word type specifiers
   other than _Complex and _Imaginary, and a typedef name as the first
   specifier only.  Within those constraints, there are no GCC extensions
   and what is accepted should be exactly what C99 permits.  All
   sequences are tested which do not have a shorter invalid initial
   subsequence.  Within the given constraints, there are no valid sequences
   with an invalid initial subsequence.

   In particular, the example of PR c/4319 should be rejected unconditionally,
   not requiring -pedantic.  */
