--- Comment #11 from Justin Bassett <jbassett271 at gmail dot com> ---
An additional use case: to test that header files can compile in isolation, one
could compile the header file with -fsyntax-only ( g++ -xc++ -fsyntax-only
myheader.hpp ). However, this emits the "#pragma once in main file" warning,
which is undesirable, especially because it makes -Werror impossible. This
means that a tool for checking header file isolation would have to emit a new
file to check header isolation.
