configure: fix unrecognized -Wno option
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!]
