Calling copyObject in C++ without GNU extensions (e.g. when using
-std=c++11 instead of -std=gnu++11) fails with an error like this:
error: use of undeclared identifier 'typeof'; did you mean 'typeid'
This is due to the C compiler used to compile PostgreSQL supporting
typeof, but that function actually not being present in the C++
compiler. This fixes that by explicitely checking for typeof support
in C++, and then either use that or define typeof ourselves as:
std::remove_reference_t<decltype(x)>
According to the paper that led to adding typeof to the C standard,
that's the C++ equivalent of the C typeof:
