Subject: [PATCH] meson: handle bool-compare warning as error
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Then we can detect the error fixed by the previous commit like the following:

../src/libsystemd/sd-device/test-sd-device.c: In function ‘test_sd_device_enumerator_add_all_parents’:
../src/shared/tests.h:225:51: error: comparison of constant ‘0’ with boolean expression is always true [-Werror=bool-compare]
  225 | #define ASSERT_OK(expr) __coverity_check__((expr) >= 0)
      |                                                   ^~
../src/libsystemd/sd-device/test-sd-device.c:547:9: note: in expansion of macro ‘ASSERT_OK’
  547 |         ASSERT_OK(sd_device_enumerator_add_all_parents(e) >= 0);
      |         ^~~~~~~~~
