This patch fixes that to print: error: 'static void CW<T>::operator=(int) requires requires(typename decltype(T())::type x) {x;}' must be a non-static member function PR c++/118139 gcc/cp/ChangeLog: * cxx-pretty-print.cc (pp_cxx_nested_name_specifier): Handle a computed-type-specifier. gcc/testsuite/ChangeLog: * g++.dg/diagnostic/decltype1.C: New test.
