In general I don't like to silence such warning because later compiler
versions are often fixed to detect such wrong warnings.  The
initialization may in some cases even inhibit the compiler to detect
other errors.

The context is initialized in do_arcfour_setkey.  Trailing commas are
not needed and HP compilers may bail out here.

I suggest not to apply this patch.
