How to install Checker ?

1) Build it with make.
   % make dep
   % make
   You should get a file libchecker.o
2) become root
   % su
3) and try make install
   % make install
   files will be installed in /usr/local/lib/checker/
   checkergcc will be installed in /usr/local/bin/
4) install the checkered c-library (See Checker-libs-V0.4.tgz)
   % cd /
   % tar zxvf Checker-libs-V0.4.tgz
4b) You can also install the X libs (See Checker-Xlibs-V0.4.tgz)
   % cd /usr/local/lib/checker
   % tar zxvf Checker-Xlibs-V0.4.tgz
   WARNING: I have not tested them.
5) use it
 to compile *.c with checker:
 checkergcc -c *.c $(CFLAGS)
 checkergcc -o my_prg *.o
 i.e. replace 'cc' or 'gcc' by 'checkergcc'
 If you want to use 'g++', you can do use 'checkerg++'
