Will -Wpedantic do anything when compiling with a non-extension -std?

If I compile my C or C++ code with GCC, using -std=c99 or -std=c++11 or some other proper ISO standard rather than a GNU extension - will -Wpedantic issue more warnings that I would usually get? e.g. With -W, -Wall or -Wall -Wextra?
