well jeff since you unhelpfully replied to this poor guy with a link to the wiki that he already got last week, allow me to be pedantic for a moment: he's not building mpich *on* windows. he's building mpich *for* windows. *On* linux.
Is the FAQ precise that building on Windows is the problem, as opposed to building for Windows? Because I have to believe the issues cannot be separated. What compiler executes on Linux that can generate Windows executables? That doesn't even seem remotely feasible, particularly if any header in MPICH is included from a sub directory, since the slashes will be wrong on a Linux file system.
I stand by my redundant response unless someone can explain the theory of how it would work.

Is possible to use mpich in order to cross compile between windows and
linux? I tried to built mpich 's libraries using mingw-w64 but nothing
done. I got many many errors. Any feedback will be helpful.
which is your target and which is your host? If you are building a linux
target on a windows host, you might be better off setting up a virtual
machine and doing your cross compilation there.
In general, cross compilation works with mpich: we do it regularly for
Blue Gene.
