Problems with gcc on FreeBSD-9.1

Hi,

gcc on FreeBSD-9.1 has a problem in CPP. It does not handle undefined macros 
correctly.

	XXX > 2 

If ther is no #define XXX, the above code has to be evaluated as if XXX has the 
value 0.

FreeBSD 9.1 introduced 

#define	__FreeBSD_kernel__

in sys/param.h which is wrong and breaks Debian kBSD compatibility.

Note that Denbian has something like:

#define	__FreeBSD_kernel__ 8

If you however use:

#if defined(_FreeBSD_kernel__) && (__FreeBSD_kernel > 2)


this now fails on FreeeBSD with:

	operator '>' has no left operand

This causes cdda2wav to fail to compile.


BTW: the FreeBSD install CD:

	FreeBSD-9.1-RELEASE-i386-bootonly.iso

uses NetBSD as system ID and in addition it seems that it has been created with 
a dubious mkisofs version:

-	Rock Ridge was withdrawn in favor of UDF, so there was never a
	IEEE P1282 standard. Thou should not use "IEEE_P1282" as ID in the
	extension record.

-	mkisofs got plenty of bug fixes in August 2006 and since then
	correctly hides the "/.rr_moved" directory. You should use a recent 
	mkisofs version for best results.
