I get the following warnings when compiling the latest linux kernel 
with the 20001225 gcc snapshot:

gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-
prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing -pipe -
mpreferred-stack-boundary=2 -march=k6    -c -o names.o names.c

imm.c:929:37: warning: trigraph ??) ignored
imm.c:938:38: warning: trigraph ??) ignored

The lines are as follows:
devlist.h:
line 1278: 	DEVICE(109e,036c,"Bt879(??) Video Capture")
line 6370:   VENDOR(2a15,"3D Vision(???)")

imm.c:
line 929: 	printk("imm: parity error (???)\n");
line 938: 	printk("imm: bad interrupt (???)\n");

>From looking at the code it is apparent to me that the authors of 
these files meant to print the string ??) and not the character ].  Is 
there a possible fix to remove these warnings or should I just ignore 
them?  I felt this would be the appropriate list to send this to since 
it compiles without these warnings with egcs-1.1.2.
