By default, C function prototypes declared in headers are visible, so there is no need to declare them as 'extern' functions. Remove this redundancy in a single bulk commit; do not modify: - meson.build (used to check function availability at runtime) - pc-bios/ - libdecnumber/ - tests/ - *.c Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Message-Id: <20230605175647.88395-5-philmd@linaro.org>
