I'm seeing tons of these type warnings:
gcc -D__KERNEL__ -I/usr/src/linux-2.4.19/include -Wall -Wstrict-prototypes -Wno-trigraphs -Os
-fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2 -march=i686 -malign-functions=4

/usr/src/linux-2.4.19/include/linux/bitops.h:78: warning: implicit declaration of function `fls'
It appears that linux/bitops.h includes asm/bitops.h, which itself
includes linux/bitops.h prior to the #define fls(x)... Both files
have include guards, therefore the #define never happens....
