To do that, this

gfc_warning_now (OPT_Wtabs,
                               "Nonconforming tab character in column %d "
                               "of line %d", i+1, linenum);

has to be replaced by this

gfc_warning_now (OPT_Wtabs, "Nonconforming tab character at %C");

or this

gfc_warning_now (OPT_Wtabs, "Nonconforming tab character at %L", where);

or

gfc_warning_now_at (location, OPT_Wtabs, "Nonconforming tab character at (1)");

Of course, the tricky part is how to set-up things such that one of those calls
will work.
