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.

Still buggy in gcc-11 (Debian 11.1.0-3) 11.1.0
I'll have a look at the code and see if I can fix it.

Another use case.
We are using precompiled headers in our application, and that includes headers
which have "#pragma once". When generating the precompiled header we get this
warning:
warning: #pragma once in main file
In that context the warning is actually invalid, so it would be really nice to
be able to turn this warning off, without turning off all warnings.
