If you have compile problems, use the configure options "--with-zlib" and
"--disable-nls" (See ABOUT-NLS).
If you have compile problems, try the configure options "--with-included-zlib"

I cant check all assembler files; so if you have problems assembling them
(or the program crashes), simply delete the files in the mpi/<cpu> directory.
