Thanks for the hint.
With the addition of __GNU_LINK  I am able to compile the code

However I have a segmentation fault running pw.x on the si.scf.david.in 
of example1.
In the zhegv routine of subroutine cdiaghg (print statement debugging)


here is the output
      Initial potential from superposition of free atoms

      starting charge = 252.96905
      Starting wfc are atomic


**** Segmentation fault!  Fault address: (nil)

This is likely to have been caused by either a null pointer dereference 
or a general protection fault.
Abort
