Here's my reasons I said not to worry: the mpi_bcast() function is the same
call, no matter whether integers or reals are being broadcast. The third
argument (mpi_integer or mpi_double_precision above) gives the
size and type of the data being transferred.
In the C language binding, the first argument of mpi_bcast is void*, which
essentially says "don't worry about what type of data this is."
There is no simple equivalent in Fortran. If you want to broadcast both
reals and integers in the same subroutine, you have to do it as written above,
and a picky compiler will issue warnings (only!) like the ones you report.
In my view, this has nothing to do with the fact that this is in NMR, nor is
there any real way to avoid it. G95 puts out warnings like this all over the
place. Until shown otherwise, I will stand by my original advice to ignore
this sort of warning.
