new example

--------------------
main.cpp
--------------------
int main()
{
  return 0;
}

--------------------
pch.h
--------------------
#include <stdio.h>

>>>>>> -g2
g++-4.7 -m64 -pipe -g2 -gdwarf-4 -fvar-tracking-assignments -Wall -W
-D_REENTRANT   -x c++-header -c pch.h -o untitled5.gch/c++
g++-4.7 -c -include untitled5 -m64 -pipe -g2 -gdwarf-4
-fvar-tracking-assignments -Wall -W -D_REENTRANT   -o main.o main.cpp
g++-4.7 -m64 -o untitled5 main.o    -L/usr/lib64 -lpthread
good
