I'd suggest to use -Wpedantic, since this is the "modern" name (and consistent with all the other -Wx flags) and it is what will be printed in the diagnostic. Moreover, -Wno-pedantic is valid, but -no-pedantic is not. With no dg-options, testcases are run with some default options, and those seem to include -pedantic-errors (no idea why).
