making two columns out of one

I've got a table containing some timesheet data.
Fields are emp, earncode, lo_shift, hi_shift.

SELECT emp, sum(hi_shift - lo_shift) as reghrs from timesheet
where earncode in ('R', 'C', 'X') order by emp

will give me all the regular hours

SELECT emp, sum(hi_shift - lo_shift) as ovrhrs from timesheet
where earncode not in ('R', 'C', 'X') order by emp

will give me all the overtime hours.

How do I combine these to get one result set with emp, reghrs, ovrhrs on
each row.
