I suggest you try the latest Bison beta, and then report back.

The lines
  out/parser.cc: In function `int yyparse(void*)':
  out/parser.cc:5583: ISO C++ forbids declaration of `yylerrsp' with  
no type
though suggests that the C parser is compiled as C++. This unofficial  
support has been dropped, for several reasons. One is that the C- 
stacks do not invoke C++ copy-constructors when reallocating. It only  
works with C++ POD's. For C++, there is no finished Bison support,  
but an experimental one. I wrote my own C++ parser, but it currently  
requires some Bison tweaks.
