Details:

When compiling hg-id 3e8bc8bee8e9 I get the following warning (edited to
remove highlighting ESC's):

libinterp/parse-tree/oct-parse.cc:475:warning: type 'yysymbol_kind_t' violates
the C++ One Definition Rule 
  475 | enum yysymbol_kind_t
      | 
libinterp/corefcn/oct-tex-parser.cc:238:note: an enum with different value
name is defined in another translation unit
  238 | enum yysymbol_kind_t
      | 
libinterp/parse-tree/oct-parse.cc:481: note: name 'YYSYMBOL_3_ESC' differs
from name 'YYSYMBOL_BF' defined in another translation unit
  481 |   YYSYMBOL_3_ = 3,                         /* '='  */
      | 
libinterp/corefcn/oct-tex-parser.cc:244:note: mismatching definition
  244 |   YYSYMBOL_BF = 3,                         /* BF  */
      | 



So far as I can see the solution is to place the C++ tex parser in a separate
namespace. For example:

%define api.namespace {octave_tex}
