#define PetscStringizeArg(a) #a
#define PetscStringize(a) PetscStringizeArg(a)
#define __SDIR__ PetscStringize(__INSDIR__)


We want __INSDIR__ to be expanded.

Looks like ${LOCDIR} is empty.

I think we should get rid of __SDIR__ entirely and just pass the full
path to the source file so that it goes into __FILE__.
