[Mpi-forum] Compile problems with examples in MPI Standard

I've run my code checker over the examples in the MPI-3 Standard, and I've found some issues. Perhaps the biggest is this (a typical example):
Opening file one-side-2.tex
ex5501.c: In function ‘main’:
ex5501.c:58: warning: passing argument 2 of ‘MPI_Init’ from incompatible pointer type
This occurs everywhere we include MPI_Init in an example. The compiler is gcc 4.2.1 . The corresponding
declaration of argv is as intended:
int main(int argc, char *argv)
The declaration in MPI_Init looks correct (argv is a pointer to an array of pointers to char). Is this a place where we should stick with the *** notation just to keep compilers happy? Or is there something I'm missing in the declaration?
There are a number of other errors as well. Three examples in the new tools chapter don't compile. There are a number of problems in the datatype chapter, most minor.
I can fix the obvious ones or leave them to the chapter authors. Let me know what is preferred.
I can't check the Fortran 08 examples because I only have gfortran :(
