As another example of bizarre compiler behavior clang groks the
-Wmaybe-uninitialized option, but not -Wno-maybe-uninitialized
and spews a warning for every file that gets compiled.
check_disable_warning -Wno-switch
check_disable_warning -Wno-format-zero-length
check_disable_warning -Wno-pointer-sign
-enabled extra_warnings || check_disable_warning -Wno-maybe-uninitialized
# add some linker flags
check_ldflags -Wl,--warn-common
check_cflags -Werror=return-type
check_cflags -Werror=declaration-after-statement
check_cflags -Werror=vla
+ enabled extra_warnings || check_disable_warning -Wno-maybe-uninitialized
elif enabled llvm_gcc; then
check_cflags -mllvm -stack-alignment=16
elif enabled clang; then
