I don't see any obvious way to, which seems a little surprising. You
might try redefining the YY_USER_ACTION macro, though (see
(flex)Miscellaneous in the Info docs):
%{
int line = 0;
int frcol = 0;
int tocol = 0;
#define YY_USER_ACTION { frcol = tocol; tocol += yyleng; }
%}
%%
\n line++; frcol = tocol = 0;
(%option yylineno will keep track of the line number for you, see
(flex)Options, but there's not an equivalent column number option that
I see. Since you need a rule for \n anyways, you might as well track
the line number by hand.)
