Hi,

gcc-6.2.1-1.fc26.x86_64

gdb compile failed, /home/jkratoch/redhat/gdb-clean/gdb/testsuite/gdb.cp/casts.cc:40:10: error: expected primary-expression before 'int'
 decltype(int x)
          ^~~
/home/jkratoch/redhat/gdb-clean/gdb/testsuite/gdb.cp/casts.cc:40:10: error: expected ')' before 'int'
/home/jkratoch/redhat/gdb-clean/gdb/testsuite/gdb.cp/casts.cc:40:1: error: expected unqualified-id before 'decltype'
 decltype(int x)
 ^~~~~~~~
/home/jkratoch/redhat/gdb-clean/gdb/testsuite/gdb.cp/casts.cc: In function 'int main(int, char**)':
/home/jkratoch/redhat/gdb-clean/gdb/testsuite/gdb.cp/casts.cc:59:14: error: expected primary-expression before 'decltype'
   double y = decltype(2);
              ^~~~~~~~

'decltype' is a registered keyword since C++11 which is now a default for GCC.

OK for check-in?
