I believe the bugs referenced here were the problem: http://gcc.gnu.org/ml/gcc-patches/2008-03/msg01680.html Both these bugs use .INTERMEDIATE in their test cases, but it isn't clear to me that this is a sufficient condition. My understanding is that the bug has been fixed in GNU make 3.82. As you point out, this has been out nearly a year; I think upgrading is not an extreme hardship. If you wanted to experiment with Makefile workarounds, I think the simplest way would be to check out the revision before the patch was reverted. Trying to apply the patch to current trunk is indeed a rathole. Tom
