;; Use decltype instead of typeof in headers
;; (Keith Seitz)

DTS11 defaults to c++17, which causes problems with the system-supplied
python headers, which use the (now forbidden) "register" storage class.

To work around this, we explicitly enable -std=c++11. However, that
now causes problems with the use of "typeof" in header files, since
-std often disables certain keywords.

Fix this by using the standard's decltype specifier instead.
