-#ifdef __linux__
+//     Rambetter's note: I'm adding the test for __FreeBSD__ in addition to the [already
+// existing] test for __linux__.  Here is why.  I own a 32 bit FreeBSD 8.0 server with
+// a PAE kernel.  Without VM_X86_MMAP, ioq3ded segfaults shortly after starting
+// (this should come as no surprise).  With VM_X86_MMAP, ioq3ded runs very smoothly.
+// So, at a very minimum, we need to set VM_X86_MMAP for FreeBSD PAE kernels.
+//     Now, I also happen to own a 32 bit FreeBSD 7.1 server with just the standard kernel
+// (non-PAE).  I have run ioq3ded successfully on it with and without VM_X86_MMAP for many
+// months.  So, in the case of non-PAE FreeBSD, we can go either way - use VM_X86_MMAP or
+// not use it.  The absolute safest fix to this problem is to only set VM_X86_MMAP on
+// PAE FreeBSD kernels (in addition to Linux); however, I don't know of a way to detect
+// the PAE kernel easily.  Therefore, since using VM_X86_MMAP won't break anything on
+// non-PAE kernels [apparently], we'll just use it all the time on FreeBSD 32 bit.
+//     Now, you may ask the question: Why not change the entire test for just __unix__?
+// Unfortunately I cannot say anything about this because I don't have access to every
+// other system that has __unix__ defined, so I cannot possibly test all those cases to
+// make sure things work.  We'll just leave it with __linux__ and __FreeBSD__ to be safe.
+// If someone with a different flavor of UNIX running a PAE kernel has this problem too,
+// they can report the bug and we will adjust the line below accordingly.
