Tue May 4 06:17pm beaky ttyp2 /usr/src/linux/scripts/ksymoops
root 3 # make
gcc -Dlinux -Wall -Wno-conversion -Waggregate-return -Wstrict-prototypes

oops.c:42: bfd.h: No such file or directory
make: *** [oops.o] Error 1

bfd.h does not appear to be in my source tree, nor anything with bfd in

All but the two above were not found - is this possibly right? Even I
couldn't have made so many typos!

Oh well, I guess getting ksymoops to compile will give me something to .
