I recall some discussion of this warning on the clang list a few months =

in a C99 or C11 dialect mode (the rationale is that any variable-length =

I suspect a lot of similar warnings are caused by the difference in =

to the cflags any modules that are using an archaic dialect of C may =
silence a lot of these...
