I think I've found what the problem is, but have no idea why it is happening.
Take a look at the following:

Linux:

	[ibraheem@sonic:~ ] 42 % uname -a
	Linux sonic 2.6.3-rc2-gentoo #2 SMP Wed Feb 18 09:12:33 GMT 2004 i686
	Pentium III (Coppermine) GenuineIntel GNU/Linux
	[ibraheem@sonic:~ ] 43 %  nawk 'BEGIN {printf "\n\n#define sigmsg(sig) ((sig) <= SIGCOUNT ? sig_msg[sig] : %c%s%c)\n", 34, "unknown signal", 34}'


	#define sigmsg(sig) ((sig) <= SIGCOUNT ? sig_msg[sig] : "unknown
	signal")
	[ibraheem@sonic:~ ] 44 %

AIX 4.3:
	
	[ibraheem@maserati:~ ] 45 % uname -a
	AIX maserati 3 4 0043CDDA4C00
	[ibraheem@maserati:~ ] 46 % nawk 'BEGIN {printf "\n\n#define sigmsg(sig) ((sig) <= SIGCOUNT ? sig_msg[sig] : %c%s%c)\n", 34, "unknown signal", 34}'


	#define sigmsg(sig) ((sig) <= SIGCOUNT ? sig_msg[sig] : "unknown signal")
	[ibraheem@maserati:~ ] 47 %

AIX 5.2

	ibraheem@md000002s:~ ] 48 % uname -a
	AIX md000002s 2 5 00541F5A4C00
	ibraheem@md000002s:~ ] 49 % nawk 'BEGIN {printf "\n\n#define sigmsg(sig) ((sig) <= SIGCOUNT ? sig_msg[sig] : %c%s%c)\n", 34, "unknown signal", 34}'


	#define sigmsg(sig) ((sig) <= SIGCOUNT ? sig_msg[sig] : "unknown signal3)
	ibraheem@md000002s: ~] 50 % 

However, it appears that /bin/nawk is the same as /bin/awk, and not a symlink as it should be.
I will attempt to compile up nawk, and use that. 

Cheers,
