a little problem about preronnie

[ghost]

In usrint.F and termn8.F in ronnie directory, inclusion of mpif.h is:

#if defined DIST_MPI
     include 'mpif.h'
#endif

which is different from source\cfl3d\dist\termn8.F:

#if defined DIST_MPI
#     include "mpif.h"
#endif

It causes some trouble when mingw-w64 gfortran is used with MS-MPI on windows platform, following TUTORIAL: Adapting MS-MPI for MinGW64 .

According to https://docs.oracle.com/cd/E19957-01/805-4939/6j4m0vna1/index.html, it can be explained as:

Files included by the preprocessor #include directive can contain #defines and the like; files included with the compiler INCLUDE statement must contain only FORTRAN statements.
