[petsc-dev] Errors from PETSc 3.11 and 3.12 headers

[Balay, Satish]

This error is strange. The issue does not come up in petsc build - but in petsc4py build.

I see the petsc4py build is with:

>>>>>>

I've attempted a petsc+petsc4py build using both the following on fedora-31 [with petsc-3.12/maint] - and there were no errors 

>>>
