Putting initialization into .cc will reduce compiler's abilities
to optimize this constant away.
Defines are not OK as they bloat global namespace.
Looking for a way to declare an efficient named constant in reduced
namespace (i. e. in  a class).
Let's try enums: normally they should be implicitly casted to int.
Let's see if we really have a compiler which won't do that.




libmysqld/lib_sql.cc:
  Added explicit cast to int for Protocol::{SEND_DEFAULTS,SEND_NUM_ROWS,
  SEND_EOF}
  flags argument of send_fields() is now int.
sql/protocol.cc:
  flags argument of send_fields is now int.
sql/protocol.h:
  Catch22: Microsoft VC++ won't compile 
  class C { static const int I=1; }.
