hi ,
i was trying to compile the file syscall.c available with the freebsd itself in the folder /usr/examples/kld/module (i guess)..
when i tried to compile the file i got the following error :
Code: 
  %gcc -o syscall syscall.c
In file included from syscall.c:35:
/usr/include/sys/systm.h:278: error: syntax error before "splbio"
/usr/include/sys/systm.h:279: error: syntax error before "splcam"

In file included from syscall.c:35:
/usr/include/sys/systm.h:38:1: unterminated #ifndef
%
i tried even to comment out the above lines giving error and i changed the permissions too using root account but still i am not able to edit the systm.h file even though it shows that after changing it has all permission for root.

Please help e in removing this error.
thanks in advance..
