Otherwise we get (harmless) errors when trying to patch a non-existent file.

See #15454.

Don't define __STRICT_ANSI__, we should build both with and without it.

For some reason, wxDialUpManager code defined __STRICT_ANSI__ itself, don't do
it as __STRICT_ANSI__ can be predefined by the compiler resulting in the
redefinition warnings and, in any case, our code should build both with and
without it.
