Mismatch in explicit fortran interface for MatGetInfo

[Barry Smith]

   Stephan,

     Thanks for reporting the problem. Our tool generates either both  
the Fortran stub and Fortran interface definition or neither. For this  
function it generates the stub correctly but the wrong interface.  The  
"quick" fix is to turn off the auto generation for this function and  
provide both manually. I'll see about making a patch. Unless someone  
has a better solution.
