Namespace-prefix

[Hans Aberg]

I am looking a bit at Bison 1.50 & C++:

I think that one might add an option
  --namespace-prefix=<name1>
in addition to the --name-prefix already present. Under C++, this option,
if non-empty, would introduce a C++ namespace <name1> {...} construct.

But one may still want to use more than one parser within the same C++
namespace, so the option
  --name-prefix=<name2>
would as before alter yy to <name2> (and when =<name2> is amiss, set yy to
empty).

Under C, if one should have some compatibility, I think that
  --namespace-prefix=<name1>
if non-empty, might prefix <name1>_ to the yynames. For example, yyparser
would become <name1>_yyparser. This is not really essential, but it would
streamline C/C++.
