    The function was already declared as static int idamax(int n, REAL *dx, int incx);
    on line 63, but it was redeclared as int idamax() inside the dgefa function on line 257,
    causing a conflict.
    where functions are redeclared without parameters,
    causing conflicts with the original function definitions.
