gcc-4.4 and later accept every -Wno option. So we can test for the option without no in the name to check if the option is supported. Each time a warning is emitted and without this fix, on gcc-4.4 that will add this warning: cc1: warning: unrecognized command line option "-Wno-unused-but-set-variable" bugs.freedesktop.org #51633, rediffed after 1.12.4 Of course this assumes that all compilers will behave like gcc, which is reasonably implicit in the set of warning flags. Signed-off-by: Gilles Espinasse <g.esp@free.fr> [ickle: slight modification to test both -W and -Wno variants to ideally preserve compatability with non-GCC compilers sharing GCC options!] |
