[antlr-interest] How to make the lexer thread-safe (C target)?

Hello,
My lexer has to rely on some internal status like the following:
DQUOTE : '"' { if(LA(-1) != '\\') double_quoted = !double_quoted;
};
SQUOTE : { double_quoted }? => '\'';
SINGLE_QUOTED_STRING_TOKEN : { !double_quoted }? => '\'' .* '\'';
"double_quoted" is a bool variable declared in @member section. The
generated code will declare it in global scope, which is not thread
safe. I wonder if there is any way to make the lexer thread-safe? For
example declare the variable in xxxLexer_Ctx_struct.
