Sorry, but the problem it is not so easy to solve.

If you read carrefully my original post, you realize that:

>madfran AT 8156 /cygdrive/c/cygwin/tmp/mpi/mpich2-1.0.6p1/examples
>$ which mpi.h /cygdrive/c/Program files/MPICH2/include/mpi.h

That means which is able to find mpi.h

>madfran AT 8156 /cygdrive/c/cygwin/tmp/mpi/mpich2-1.0.6p1/examples
>$ echo 
$PATH//usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/cygdrive/c/cygwin/lib:/cygd
rive/c/Program files/MPICH2/lib:/cygdrive/c/Program files/MPICH2/include:.....

That means the PATH is correct.

>madfran AT 8156 /cygdrive/c/cygwin/tmp/mpi/mpich2-1.0.6p1/examples
>$ ls -l /cygdrive/c/"Program Files"/MPICH2/include/mpi.h -rwxrwxrwx+ 1 
madfran root 51473 Oct 30 16:05 /cygdrive/c/Program Files/MPICH2/include/mpi.h

That means I have rights over mpi.h
