-#if defined(__FreeBSD__) && __FreeBSD_version__ >= 500023
+#if defined(__FreeBSD__) && __FreeBSD_version >= 500023
is a genuine bug -- __FreeBSD_version__ does not exist.
The other one:
-#if (__FreeBSD__ < 5)
+#if (__FreeBSD_version < 500000)
pops out when you cross-compile the code:
__FreeBSD__ is a compiler predefine,
__FreeBSD_version is defined in <sys/param.h> .
Given that in this case (and all others in sys/dev/usb and sys/i4b)
the goal is to adapt to a different kernel interface, and not to
a compiler feature, I believe the correct form is the second one
(in the best case the two are synonyms so the change does not break
anything anyways).
