[petsc-dev] removing PETSC_NULL?

[Karl Rupp]

Hi,

I'm in favor of getting rid of PETSC_NULL. We will otherwise always have 
to torture users sending patches.

As a side note, there are also uses of
  my_ptr = (void*)0;
which are not included in the 272 occurrences. Am I correct to assume 
that the rhs should be replaced with NULL in these cases?

Best regards,
Karli
