  The kchecker script prints its warnings to stdout.
  
+ The above scripts will ensure that any ARCH or CROSS_COMPILE environment
+ variables are passed to kernel build system - thus allowing for the use of
+ Smatch with kernels that are normally built with cross-compilers.
+ 
  If you are building something else (which is not the Linux kernel) then use
  something like:
  
          make CHECK="~/progs/smatch/devel/smatch --full-path" \
                  CC=~/progs/smatch/devel/smatch/cgcc | tee smatch_warns.txt
