From the below I am assuming that PETSC_USE_EXTERN_CXX is equivalent to
--with-c-support Is this correct?
And I assume that --with-c-support means that PETSc is compiled with C++ but
does not use name mangling Is this correct?
If the above two are correct does the name PETSC_USE_EXTERN_CXX actually
correlate to what it means? Could it be changed to something meaningful?
Please explain,
Barry

#error "PETSc configured with --with-clanguage=c++ and NOT --with-c-support -
