[petsc-dev] syntax error in petscmat.h90/petscvec.h90

[Alexander Grayver]

Hi Jed,

For me the fix was to delete & in case there is empty line after it. But 
I guess this situation might be fixed in your generator since anyway 
such a construction makes no sense:

subroutine VecGhostUpdateBegin(g, insertmode, scattermode ,ierr)&
&

and is equal to:

subroutine VecGhostUpdateBegin(g, insertmode, scattermode ,ierr)

Regards,
Alexander
