QtWebkit fails to compile with bison 3.0

Excerpt from compile:

g++ -c [...] -o .obj/release-shared/generated/glslang_tab.o generated/glslang_tab.cpp
generated/glslang_tab.cpp: In function 'int yyparse(TParseContext*)':
generated/glslang_tab.cpp:1785:30: error: too few arguments to function 'int yylex(YYSTYPE*, void*)'
yychar = yylex (&yylval);
^
generated/glslang_tab.cpp:279:12: note: declared here
extern int yylex(YYSTYPE* yylval_param, void* yyscanner);

Note that reverting to Bison 2.7.1 causes the compile to succeed.
