+    dnl qemu 0.15 was released with broken support for '-machine',
+    dnl requiring you to add the machine type: '-machine pc,[...]'.
+    dnl The problem is that 'pc' is only applicable for PC-like
+    dnl hardware, so we cannot do this as a general solution.  Since
+    dnl qemu 0.15, this problem has been fixed so now the default
+    dnl machine type is chosen (qemu commit 2645c6dcaf6ea2a51a).
+    dnl
+    dnl We need to work out if this qemu is the broken version, so we
+    dnl can add 'pc' just for this broken version.
+    dnl
+    dnl Note that old qemu didn't support the '-machine' option at all.
+    dnl
+    dnl We use the -kernel option for testing this, because this option
+    dnl is processed very late, after qemu has set up the machine.
