We present extended simulations of high-temperature QCD for four flavors of staggered fermions with intermediate masses. We find no evidence for a first-order transition with a quark mass of 0.2 with four time slices. Thus, our results support the picture of separated transitions for the pure gauge theory ({ital m}{sub {ital q}}{r arrow}{infinity}) and QCD with light quarks.
