symbols. Use it for all definitions of non-static variables and functions. lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static. It is referenced from pars0grm.c. Actually, according to nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]' the following symbols are still global: * The vtable for class ha_innodb * pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs The required changes to the Bison-generated file pars0grm.c will be addressed in a separate commit, which will add a script similar to make_flex.sh. The class ha_innodb is renamed from class ha_innobase by a #define. Thus, there will be no clash with the builtin InnoDB. However, there will be some overhead for invoking virtual methods of class ha_innodb. Ideas for making the vtable hidden are welcome. -fvisibility=hidden is not available in GCC 3.
